專利名稱:白色念珠菌(C.Albicans)中的必需基因及用該基因篩選抗真菌物質(zhì)的方法
技術(shù)領(lǐng)域:
本發(fā)明涉及一種篩選抗真菌物質(zhì)方法,其中真菌中,特別是白色念珠菌(Candida A1bicans,C.Albicans)中的必需基因,以及其它病原體真菌中的功能相似基因,或者相應(yīng)的編碼蛋白被用作靶。本發(fā)明也涉及特定的白色念珠菌基因。
已知真菌感染的范圍,從真菌侵蝕皮膚或者指甲到對(duì)內(nèi)臟器官潛在的真菌感染;這種感染和由其造成的疾病被稱為真菌病。
抗真菌物質(zhì)(抑真菌的或者殺真菌的)被用于治療真菌病。然而,直到現(xiàn)在,已知具有病理效果的這種物質(zhì)相對(duì)很少,例如,兩性霉素B(Amphotericin B),制霉菌素(Nystatin),匹馬霉素(Pimaricin),灰黃霉素(Griseofulvin),克霉唑,5-氟-胞嘧啶(5-fluoro-cytosine)和Batraphene。藥物治療真菌感染非常困難,特別是因?yàn)樗拗骷?xì)胞和真菌都是真核細(xì)胞。因此,基于已知的抗真菌物質(zhì)來(lái)用藥,經(jīng)常造成不希望有的副作用,例如,兩性霉素B具有腎毒性的作用。所以,強(qiáng)烈地需求可用于制造藥品的病理有效性物質(zhì),這樣的藥品適用于預(yù)防治療免疫抑制狀態(tài)或者是治療已存在的真菌感染。另外,這種物質(zhì)應(yīng)當(dāng)表現(xiàn)出特定的作用譜,以選擇性的抑制真菌的生長(zhǎng)和繁殖而并不影響被治療的宿主生物。
本發(fā)明的目的是為了提供一種鑒別抗真菌物質(zhì)的方法,尤其是用于鑒別抗念球菌屬(Candida)物質(zhì)的方法。該方法的必要特征是把真菌的必需基因作為篩選的靶。
因此本方法涉及一種篩選抗真菌物質(zhì)的方法,其中該真菌的必需基因,或者是其它病原體真菌的功能相似基因,或者是相應(yīng)的編碼蛋白被用作靶,該必需基因選自CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325和CaJL039。
根據(jù)本發(fā)明這一方法的一種實(shí)施方案,將以不同水平表達(dá)其必需基因或者是功能相似真菌基因的真菌細(xì)胞與被測(cè)試物質(zhì)一起保溫,并測(cè)定該物質(zhì)的生長(zhǎng)抑制效果。
根據(jù)另一種實(shí)施方案,將該靶基因或者是該靶基因編碼的相應(yīng)蛋白,在體外與被測(cè)試物質(zhì)接觸并測(cè)定該物質(zhì)對(duì)于靶的效果。
根據(jù)另一種實(shí)施方案,被篩選物質(zhì)部分或者完全地抑制該必需基因的功能表達(dá)或者其編碼蛋白的功能活性。
根據(jù)一種實(shí)施方案,被篩選物質(zhì)部分或者完全地抑制二氫蝶酸合酶(dihydropteroate synthase)(DHPS)和/或7,8-二氫-6-羥甲基蝶呤-焦磷酸激酶(HPPK)的活性。
根據(jù)另一種實(shí)施方案,真菌的種選自擔(dān)子菌屬(Basidiomycetes),子囊菌屬(Ascomycetes)和絲孢菌屬(Hyphomycetes)。
根據(jù)本發(fā)明這一方法的另一種實(shí)施方案,該功能相似基因是念珠菌屬的種(Candida Spp.),特別是白色念珠菌的必需基因,或者是曲霉屬的種(Aspergillus Spp.),特別是煙曲霉的必需基因。
根據(jù)另一方面,本發(fā)明涉及一種多核苷酸,其同系物和其功能片斷,該多核苷酸具有SEQ ID No.2,SEQ ID No.4,SEQ ID No.6,SEQID No.7,SEQ ID No.9,SEQ ID No.10,SEQ ID No.11或SEQ ID No.13所示的序列,優(yōu)選具有SEQ ID No.2,SEQ ID No.4,SEQ ID No.6,SEQ ID No.9,SEQ ID No.10或SEQ ID No.11所示的序列。
根據(jù)另一方面,本發(fā)明涉及一種基因或其功能相似基因或其功能片段,該基因是CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或者CaJL039,優(yōu)選是CaOR110,CaMR212,CaNL256,CaBR102或者CaIR012。
根據(jù)這一實(shí)施方案,功能相似基因或者同源的多核苷酸,在核苷酸水平上,分別與CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或者CaJL039,有至少50%優(yōu)選為至少60%,最優(yōu)選為至少70%的序列同一性。其功能片斷是一種多核苷酸片斷,它保留了起始產(chǎn)物(核苷酸或基因)的功能性。一個(gè)實(shí)例就是CaOR110的剪接變體(它也與原始基因同源,具有大約90%的同一性)。
根據(jù)另一種實(shí)施方案,功能相似基因,在氨基酸水平上,分別與CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或者CaJL039編碼的蛋白質(zhì),有至少40%,優(yōu)選至少50%,更優(yōu)選至少60%,最優(yōu)選有至少70%的序列同一性。
就同源性和相似性而言,這些對(duì)基因的描述,加以必要的修正后也適用于多核苷酸。
根據(jù)另一方面,本發(fā)明包括分別由CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或CaJL039基因,或其功能相似基因編碼的蛋白質(zhì)或其功能性的多肽片段。
根據(jù)另一方面,本發(fā)明提供了一種分別含有CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或CaJL039基因,或其功能相似基因,或其功能片斷的質(zhì)粒。
根據(jù)另一方面,本發(fā)明提供了一種在1998年8月13日保藏于CNCM(巴斯德研究所,巴黎)的質(zhì)粒(含有該質(zhì)粒的細(xì)菌),其編號(hào)為I-2065,I-2063和I-2064,分別對(duì)應(yīng)CaNL256,CaBR102和CaIR012基因。
根據(jù)另一方面,本發(fā)明提供了一種在1999年8月6日保藏于DSMZ(德國(guó)微生物和細(xì)胞培養(yǎng)物保藏中心)的質(zhì)粒(含有該質(zhì)粒的細(xì)菌),其編號(hào)為DSM12977,DSM12976,DSM12978和DSM12979,分別對(duì)應(yīng)CaDR325,CaOR110,CaOR110剪接變體和CaMR212。
根據(jù)另一方面,本發(fā)明提供了一種試劑盒,該試劑盒可用于診斷真菌感染,所述試劑盒中包括選自CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325和CaJL039的基因,其功能相似基因,其功能片斷,相應(yīng)編碼蛋白或者其功能性多肽片斷。

根據(jù)另一方面,本發(fā)明提供了一種多核苷酸,該多核苷酸可通過(guò)包括以下步驟的方法獲得(i)從釀酒酵母(Saccharomyces cerevisiae)中選擇一種必需基因;(ii)比較該基因的序列與白色念珠菌的基因組序列;(iii)推斷寡核苷酸同源區(qū)域;(iv)PCR擴(kuò)增如此獲得的寡核苷酸;(v)用步驟(iv)的擴(kuò)增引物探測(cè)感興趣的完整基因步驟(iv)的擴(kuò)增引物被用作探針,從白色念珠菌的基因組庫(kù)或者cDNA文庫(kù)中探測(cè)感興趣的完整基因;或者通過(guò)擴(kuò)增引物3’-和5’-末端的延伸,例如用一種PCR方法來(lái)獲得完整的基因。
根據(jù)本發(fā)明,第一步是鑒定所說(shuō)的必需基因,由這些基因出發(fā),可以鑒定其它病原體真菌中的必需基因。為了應(yīng)用的目的,釀酒酵母中的必需基因被首先鑒定,由這些基因出發(fā),得到其它病原體真菌,特別是念珠菌的必需基因。
于是,本發(fā)明公開(kāi)了白色念珠菌中必需基因的鑒定,以及這些基因在一種篩選抗真菌物質(zhì),特別是抗念珠菌物質(zhì)的方法中的用途。
為了鑒定釀酒酵母中的必需基因,通過(guò)同源重組消除單個(gè)的基因組基因。如果這樣消除的DNA區(qū)斷涉及必需基因,那么這樣的缺失對(duì)于以單倍體形式存在的釀酒酵母細(xì)胞是致命的。
一種方法可以用于產(chǎn)生相應(yīng)的基因組缺失的釀酒酵母,并且可以確定含有缺失的釀酒酵母細(xì)胞,該方法中所研究的釀酒酵母基因被標(biāo)記基因所取代。
例如,顯性選擇性標(biāo)記(例如,卡那霉素抗性基因)或者營(yíng)養(yǎng)缺陷型標(biāo)記可用作選擇性標(biāo)記。對(duì)于營(yíng)養(yǎng)缺陷型標(biāo)記,它可能使用編碼氨基酸或者核酸堿基合成的關(guān)鍵酶的基因。例如,下列釀酒酵母的基因可被用作選擇性標(biāo)記編碼亮氨酸代謝途徑的基因(例如,LEU2-基因),編碼組氨酸代謝途徑的基因(例如,HIS3-基因),或編碼色氨酸代謝途徑的基因(例如,TRP-1-基因),或者編碼尿嘧啶核酸堿基代謝途徑的基因(例如,URA3-基因)。
釀酒酵母的營(yíng)養(yǎng)缺陷型菌株可以使用。這些營(yíng)養(yǎng)缺陷型菌株只能在含有相應(yīng)氨基酸或者核苷酸堿基的營(yíng)養(yǎng)培養(yǎng)基上生長(zhǎng)。例如,所有含有營(yíng)養(yǎng)缺陷型標(biāo)記的實(shí)驗(yàn)室釀酒酵母菌株都可以使用。當(dāng)使用雙倍體釀酒酵母菌株時(shí),相應(yīng)的標(biāo)記基因必須被純合突變??梢允褂镁闏EN.PK2或其同基因的衍生物。
沒(méi)有合適營(yíng)養(yǎng)缺陷型標(biāo)記的菌株也可以使用,例如原養(yǎng)型釀酒酵母菌株。因而可以使用顯性選擇性標(biāo)記,例如象是卡那霉素抗性基因這樣的抗性基因。loxP-KanMX-loxP盒可方便地用于這一目的。
為了用同源重組替換釀酒酵母基因的整個(gè)DNA序列或其部分,使用了DNA片斷,其中,標(biāo)記基因在5’-和3’-末端與所研究的釀酒酵母基因的5’-和3’-末端同源序列側(cè)接。
可以使用不同的方法來(lái)制備相應(yīng)的DNA片斷,這些DNA片斷適用于缺失任何特定的釀酒酵母基因。一種線性DNA片斷被用于轉(zhuǎn)化合適的釀酒酵母菌株。這種片斷通過(guò)同源重組被整合到釀酒酵母基因組中。這種方法包括1.制備缺失盒的“傳統(tǒng)方法”(Rothstein,R.J.(1993)酶學(xué)方法,Vol.101,202-211)。
2.使用PCR技術(shù)的“傳統(tǒng)方法”(“經(jīng)過(guò)修改的傳統(tǒng)方法”)。
3.SFH(short flanking homology)-PCR方法(Wach,A.等(1994)酵母101793-1808;Gültner,U.等(1996)核酸研究242519-2524)。
1.在制備釀酒酵母基因組缺失盒的“傳統(tǒng)方法”中,待研究基因或者已經(jīng)存在于合適的載體中,或者被整合到這樣的載體中。用這種方法,任何pBR-,pUC-和pBluescript@-衍生物都可用于實(shí)例。靶基因的一段重要部分被從載體中缺失,例如使用合適的限制性性酶切位點(diǎn),但是載體中要保存待研究基因的3’-和5’-末端區(qū)域。選出的標(biāo)記基因被整合到保留的區(qū)域之間。
2.在“經(jīng)過(guò)修改的傳統(tǒng)方法”中使用了PCR。這種方法可以擴(kuò)增所研究的釀酒酵母基因編碼序列3’-末端和5’-末端區(qū)域。這種方法可以選擇性地?cái)U(kuò)增所研究基因的兩個(gè)末端區(qū)域,因此,對(duì)每一個(gè)所研究基因,必須進(jìn)行兩次PCR反應(yīng),一次擴(kuò)增5’-末端區(qū)域,一次擴(kuò)增3’-末端區(qū)域。擴(kuò)增末端DNA-片斷的長(zhǎng)度依賴于已存在的限制性酶切位點(diǎn)。被擴(kuò)增的所研究基因末端的通常長(zhǎng)度是50到5000堿基對(duì)(bp),優(yōu)選長(zhǎng)度是500到1000bp。
釀酒酵母的基因組DNA或者野生型基因可被用作PCR反應(yīng)的模板。構(gòu)建引物對(duì)(有義引物和反義引物各一),要使它們對(duì)應(yīng)與所研究釀酒酵母基因的3’-末端和5’-末端序列。為了通過(guò)合適的限制性酶切位點(diǎn)整合,尤其要選擇合適的引物。
pBR-pUC-,pBluescript-衍生物都可用作載體。已經(jīng)含有編碼選擇性標(biāo)記基因的載體是特別合適的。尤其是可以使用含有選擇性標(biāo)記HIS3,LEU2,TRP1或URA3基因的載體。
通過(guò)PCR獲得的所研究釀酒酵母基因的DNA區(qū)段,被整合到載體中選擇標(biāo)記的兩側(cè),于是隨后,像在傳統(tǒng)方法中那樣,選擇標(biāo)記的兩端與所研究基因的同源DNA序列末端側(cè)接。
3.釀酒酵母中的同源重組以一種非常有效非常精確的方式進(jìn)行,實(shí)際上,與選擇性標(biāo)記基因側(cè)接的所研究釀酒酵母基因的同源DNA序列的長(zhǎng)度,可以比“修改的傳統(tǒng)方法”中的短許多。與所研究釀酒酵母基因同源的側(cè)翼末端所需的長(zhǎng)度只要大約20-60bp,優(yōu)選為30-45bp。SFH-PCR方法是非常優(yōu)越的,因?yàn)榭梢员苊馐褂觅M(fèi)力的克隆步驟。
PCR反應(yīng)在含有要用到的選擇性標(biāo)記基因的DNA模板上進(jìn)行,構(gòu)建引物,使有義引物的DNA序列與選擇性標(biāo)記序列的5’-末端同源,引物的5’-末端還要多出最好40個(gè)核苷酸,這些多出的核苷酸要與所研究釀酒酵母基因的5’-末端序列相對(duì)應(yīng)。反義引物以類似的方式構(gòu)建,即反義引物與選擇性標(biāo)記基因序列的3’-末端互補(bǔ),其中,該引物在其5’-末端還要多出一段最好也是40個(gè)核苷酸的區(qū)域,這段區(qū)域要與所研究基因的3’-末端編碼序列的互補(bǔ)鏈相對(duì)應(yīng)。
含有營(yíng)養(yǎng)缺陷型標(biāo)記基因或者選擇性標(biāo)記基因的載體,可以用于通過(guò)SFH-PCR方法擴(kuò)增所研究的釀酒酵母基因。特別是質(zhì)粒pUG6可用作模板。這種質(zhì)粒含有一個(gè)loxP-KanMX-loxP盒(Gültner,U.等(1996)核酸研究242519-2524)。換句話說(shuō)就是,卡那霉素抗性基因側(cè)接在loxP序列(loxP-KanMX-loxP盒)的兩端。這種盒非常優(yōu)越,因?yàn)榭敲顾乜剐曰蚩梢酝ㄟ^(guò)將loxP-KanMX-loxP盒整合到所研究釀酒基因中,而最終從釀酒酵母基因組中除去。噬菌體P1的Cre-重組酶可用于這一目的。Cre-重組酶識(shí)別loxP序列并且通過(guò)同源重組過(guò)程誘導(dǎo)位于兩段loxP序列之間的DNA的消除。結(jié)果,只有一個(gè)loxP序列保留下來(lái),并且發(fā)生了所謂的標(biāo)記再生,即釀酒酵母菌株可以用loxP-KanMX-loxP盒進(jìn)行再次轉(zhuǎn)化。當(dāng)為了得到致死表型,而至少要缺失兩個(gè)功能相似基因時(shí),這一點(diǎn)便顯得特別有利。
對(duì)于PCR方法來(lái)說(shuō),PCR反應(yīng)引物在3’-末端優(yōu)選有20個(gè)核苷酸長(zhǎng)的序列,這段序列與位于loxP-KanMX-loxP盒左側(cè)或者右側(cè)的序列同源,而在5’-末端優(yōu)選有40個(gè)核苷酸長(zhǎng)的序列,這段序列與所研究基因的末端同源。
使用這三種方法,可以得到含有編碼選擇標(biāo)記基因的線性缺失盒,該盒兩端側(cè)接有所研究基因的源序列。缺失盒被用于轉(zhuǎn)化二倍體釀酒酵母菌株。二倍體釀酒酵母菌株CEN.PK2(Scientific Research&Development Gmbh,Oberursel)可用作這一目的的實(shí)例。CEN.PK2菌株用已知方法準(zhǔn)備并培養(yǎng)(Gietz,R.D.等(1992)核酸研究81425;Gültner,U.等(1996)核酸研究242519-2524)。
根據(jù)已知方法,用合適DNA數(shù)量的線性缺失盒轉(zhuǎn)化所用的釀酒酵母菌株的細(xì)胞(例如,Sambrook等1989)。之后,用一種新的所謂的選擇培養(yǎng)基替換培養(yǎng)細(xì)胞的培養(yǎng)基,這種選擇培養(yǎng)基不含有相應(yīng)的氨基酸(例如,組氨酸,亮氨酸或者色氨酸)或者核苷堿基(例如,尿嘧啶),或者當(dāng)使用含有卡那霉素抗性基因的缺失盒時(shí),用含有遺傳霉素(G418)的培養(yǎng)基(例如,含有的遺傳霉素的完全培養(yǎng)基(YEPD))替換培養(yǎng)細(xì)胞的培養(yǎng)基。另一種選擇是,把轉(zhuǎn)化的細(xì)胞接種到用相應(yīng)培養(yǎng)基制備的瓊脂平板上。從而,可以選擇出在其中發(fā)生了同源重組的轉(zhuǎn)化細(xì)胞,因?yàn)橹挥心切┘?xì)胞可以生長(zhǎng)在這種經(jīng)修飾的條件下。
然而,在大多數(shù)情況下,在轉(zhuǎn)化過(guò)程中,二倍體釀酒酵母菌株位于一對(duì)染色體的基因的兩個(gè)拷貝中,只有一個(gè)被DNA缺失盒取代,從而產(chǎn)生了雜合子二倍體釀酒酵母突變株,其中所研究基因的一個(gè)拷貝被選擇性標(biāo)記取代,而基因的另一個(gè)拷貝仍保留在基因組中。這就體現(xiàn)了一種優(yōu)越性,即因?yàn)榇嬖诒匦杌虻牡诙€(gè)拷貝,所以當(dāng)萬(wàn)一缺失了一個(gè)必需基因時(shí),釀酒酵母突變體仍可以存活。
缺失盒DNA在預(yù)定染色體基因座(所研究基因的基因座)的適當(dāng)整合,可以通過(guò)Southern印跡分析(Southern,E.M.(1975)分子生物學(xué)雜志98503-517)或者使用特殊引物的診斷PCR分析(Gültner,U.等(1996)核酸研究242519-2524)來(lái)檢查。
單個(gè)二倍體細(xì)胞的遺傳分離可以通過(guò)四分體分析進(jìn)行監(jiān)控。為此,使用如氮貧乏的乙酸鉀平板這樣的已知方法,誘導(dǎo)二倍體細(xì)胞,特別是雜合子突變株,進(jìn)行減數(shù)分裂。(Sherman,F(xiàn).等(1986)冷泉港實(shí)驗(yàn)室出版社,冷泉港,紐約;Guthrie,C.和Fink,G.R.(1991)酶學(xué)方法,Vol 194.Academic Press,San Diego,3-21;Ausubel,F(xiàn).M.等(1987)分子生物學(xué)最新方法John Wiley和Sons,Inc.,Chapter 13)。減數(shù)分裂造成只有四個(gè)子囊孢子的子囊(經(jīng)過(guò)分離的),在用酶解酶部分酶解子囊壁后,可以通過(guò)顯微操作器(例如SINGER)得到單個(gè)的子囊孢子(Ausubel等(1987))。當(dāng)對(duì)一雜合子二倍體突變株進(jìn)行四分體分析時(shí),該二倍體突變株一對(duì)染色體上的一個(gè)必需基因已經(jīng)經(jīng)同源重組被取代,只有兩個(gè)分離的子囊孢子,即那些攜帶有必需基因的可以存活。其余兩個(gè)分離的子囊孢子因?yàn)槿鄙僭摫匦杌蚨荒艽婊睢?br>
為了檢查通過(guò)這種方法研究的基因是否真的必需,以及同源重組是否導(dǎo)致一個(gè)必需基因的位置發(fā)生變化而與所研究基因的基因座相鄰,釀酒酵母雜合子二倍體突變株用含有該研究基因的著絲粒質(zhì)粒進(jìn)行轉(zhuǎn)化。
對(duì)轉(zhuǎn)化體進(jìn)行四分體分析。當(dāng)?shù)玫剿膫€(gè)而不是兩個(gè)可存活分離子時(shí),包含在著絲粒質(zhì)粒中的所研究基因,可以彌補(bǔ)那兩個(gè)不能存活的釀酒酵母單倍體細(xì)胞/突變株的缺陷,這就證明了所研究的釀酒酵母基因是必需的。
優(yōu)選用拷貝數(shù)比較少,例如每個(gè)細(xì)胞有一到兩個(gè)拷貝的質(zhì)粒作為著絲粒質(zhì)粒。例如質(zhì)粒pRS313,pRS314,pRS315和pRS316(Sijkorski,R.S.和Hieter,P.(1989)遺傳學(xué)12219-27)或者可用于這一目的的類似質(zhì)粒。所研究基因優(yōu)選是連同其3’-末端和5’-末端非編碼區(qū)一起整合到所說(shuō)的質(zhì)粒中。
序列全部或者部分已知的各個(gè)釀酒酵母基因可以用上述方法進(jìn)行研究。完整的釀酒酵母基因組序列于1996年4月24日通過(guò)WWW(國(guó)際互聯(lián)網(wǎng))對(duì)公眾公開(kāi)。

用這種方法已經(jīng)鑒定了7種釀酒酵母基因組必需基因YDR325w,YJL039c,YOR110w,YNL256w,YBR102c,YIR012W和YMR212c。
然后釀酒酵母的必需基因被用來(lái)鑒定其它真菌相應(yīng)的功能相似基因。
其它真菌中的功能相似基因,是指與所鑒定的釀酒酵母必需基因功能相似或相同的基因。其它真菌中的功能相似基因,可以但不是必須與相應(yīng)的釀酒酵母必需基因序列同源。其它真菌中的功能相似基因,在核苷酸水平上,可以只表現(xiàn)出與相應(yīng)的釀酒酵母必需基因中等程度的序列同源性。中等程度的序列同源,在本發(fā)明中是指,在核苷酸水平上要有至少50%的序列同一性,更優(yōu)選有至少60%的序列同一性,最優(yōu)選有至少70%的序列同一性。
另外,其它真菌中的功能相似基因,可以但不是必須編碼與相應(yīng)的釀酒酵母必需基因編碼的蛋白質(zhì)序列同源的蛋白質(zhì)。其它真菌中的功能相似蛋白質(zhì),可以只表現(xiàn)出與相應(yīng)的釀酒酵母必需基因編碼的蛋白質(zhì)中等程度的蛋白質(zhì)序列同源性。
中等程度的蛋白質(zhì)序列同源性,在本發(fā)明中是指,在氨基酸水平上要有至少40%的序列同一性,優(yōu)選有至少50%的序列同一性,更優(yōu)選有至少60%的序列同一性,最優(yōu)選有至少70%的序列同一性。
序列同源基因可以通過(guò)已知方法分離,例如通過(guò)同源篩選(Sambrook,J.等(1989)分子克隆,冷泉港實(shí)驗(yàn)室出版社,紐約),或者通過(guò)使用來(lái)自相應(yīng)真菌基因組文庫(kù)和/或cDNA文庫(kù)的特殊引物的PCR技術(shù)。
根據(jù)一種實(shí)施方案,從cDNA文庫(kù)中分離序列同源基因。為了找出其它真菌中的功能相似基因,根據(jù)已知方法從所研究真菌中分離出mRNA(Sambrook,等1989),根據(jù)已知方法合成cDNA(Sambrook,等1989;或cDNA合成試劑盒,如STRATAGENE)。
制備的cDNA被定向整合到合適的表達(dá)載體中。
例如,考慮到表達(dá)載體的啟動(dòng)子,為了使隨后的克隆可以適當(dāng)?shù)亩ㄎ?,第一條cDNA鏈的合成可以在具有適當(dāng)限制性酶切位點(diǎn)的引物存在下進(jìn)行。任何已知的限制性酶切位點(diǎn)可以用作限制性酶切位點(diǎn)。關(guān)于引物,可以使用50個(gè)核苷酸長(zhǎng)的引物,例如以下引物5′-GAGAGAGAGAGAGAGAGAGAACTAGTXXXXXXTTTTTTTTTTTTTTTTTT-3′序列(X)6表示適當(dāng)?shù)南拗菩悦盖形稽c(diǎn),例如XhoI的限制性酶切位點(diǎn)。
合成完雙鏈之后,雙鏈cDNA的粘性末端被補(bǔ)平(鈍端),然后cDNA末端用合適的DNA連接序列連接。DNA連接序列應(yīng)當(dāng)包含一個(gè)限制性酶切位點(diǎn),該限制性酶切位點(diǎn)應(yīng)當(dāng)與在合成第一條cDNA鏈時(shí)使用的引物中的限制性酶切位點(diǎn)不同。DNA連接序列可以包含例如互補(bǔ)的9或13聚體寡核苷酸,其末端代表限制性酶切位點(diǎn)的粘性末端。例如,這樣的末端可以是EcoRI-位點(diǎn)5′XXXXXGGCACGAG 3′3′XCCGTGCTC 5′連接序列中的單鏈X表示限制性酶切位點(diǎn)的粘性末端。
然后,用限制性內(nèi)切酶酶切具有相應(yīng)連接序列的cDNA,該限制性內(nèi)切酶的識(shí)別位點(diǎn)被使用在合成第一條cDNA鏈時(shí)使用的引物中,例如XhoI。根據(jù)這個(gè)實(shí)例,如此得到的cDNA具有3’-XhoI和5’-EcoRI突出末端,所以可以被定向整合到經(jīng)XhoI和EcoRI酶切的表達(dá)載體中。
在其它載體中,大腸桿菌/釀酒酵母穿梭載體,即在大腸桿菌和釀酒酵母都可以使用的載體,是合適的表達(dá)載體。這種載體可以在例如大腸桿菌中擴(kuò)增。那些在釀酒酵母中具有高拷貝數(shù)的載體和具有低拷貝數(shù)的載體都可以用作表達(dá)載體。為了這一目的,例如,選自pRS423-pRS426(pRS423,pRS424,pRS425,pRS426)和/或pRS313-pRS316(pRS313,pRS314,pRS315,pRS316)(Sikorki,R.S.和Hieter,P.(1989)遺傳學(xué)12219-27;Christianson T.W.等(1992)基因110119-122)的載體都是適合的。
表達(dá)載體應(yīng)當(dāng)含有合適的釀酒酵母啟動(dòng)子和終止子。萬(wàn)一這些載體不含有這些元件,那么相應(yīng)啟動(dòng)子和終止子的插入應(yīng)使得隨后仍可能摻入所產(chǎn)生的cDNA。釀酒酵母基因MET25,PGK1,TPI1,TDH3,ADHI,URA3的啟動(dòng)子特別合適作啟動(dòng)子。可以使用未修飾形式的野生型基因的啟動(dòng)子,也可以使用經(jīng)過(guò)除去某些激活子序列和/或阻抑蛋白序列方式而修飾過(guò)的啟動(dòng)子。例如,釀酒酵母基因MET25,PGK1,TPI1,TDH3,ADHI,URA3的終止子適合于作終止子。
根據(jù)另一種實(shí)施方案,從基因組文庫(kù)中分離序列同源基因??梢愿鶕?jù)已知方法制備真菌基因組DNA文庫(kù)(例如象在分子生物學(xué)最新方法,John Wiley和Sons,Inc中所描述的)。例如,可以通過(guò)已知的裂解酵母細(xì)胞和分離基因組DNA的方法制備真菌基因組DNA(例如Bio101,Inc的商品試劑盒)?;蚪MDNA可以用限制性酶,例如Sau3AI,進(jìn)行部分酶解,酶解片段用瓊脂糖凝膠電泳進(jìn)行大小選擇。例如,5-10kb大小的DNA片段可以用經(jīng)典方法純化(例如使用Bio101的Gene Clean試劑盒),并插入象是YEP24這樣的經(jīng)限制性酶切而具有匹配末端(例如,針對(duì)經(jīng)Sau3AI酶切的基因組DNA的BamHI)的大腸桿菌/釀酒酵母穿梭載體(例如Sanglard D.,Kuchler K.,Ischer F.,Pagani J-L.,Monod M.和Bille J.,抗微生物藥劑和化學(xué)療法,(1995)Vol.39 No11,P2378-2386所描述的)。
為了從所研究真菌中發(fā)現(xiàn)與釀酒酵母必需基因功能相似的基因,一個(gè)釀酒酵母必需基因被置于可調(diào)節(jié)啟動(dòng)子的控制下,或者作為整合基因(1)或者作為染色體外基因(2)。
1.為了把可調(diào)節(jié)啟動(dòng)子整合到釀酒酵母基因組中,可以用可調(diào)節(jié)啟動(dòng)子替換選定的必需基因的天然啟動(dòng)子,例如可以用PCR進(jìn)行同源重組(Güldener,U.等(1996)。用PCR進(jìn)行同源重組可以在例如二倍體釀酒酵母菌株CEN.PK2中進(jìn)行。是否成功地整合到染色體組中,可以通過(guò)在單倍體細(xì)胞中隨后進(jìn)行的四分體分析進(jìn)行檢測(cè)。
使用四分體分析可以得到四個(gè)存活的子囊孢子,在其中的兩個(gè)單倍體分離子中,選定必需基因在天然啟動(dòng)子的控制之下,而在其余兩個(gè)分離子中,必需基因在可調(diào)節(jié)啟動(dòng)子的控制之下。
最后提到的單倍體分離子被出現(xiàn)在重組載體中的cDNA或者基因組DNA轉(zhuǎn)化。
2.使用染色體外變體,選定釀酒酵母必需基因首先被插入合適的表達(dá)載體中,例如大腸桿菌/釀酒酵母穿梭載體。為此,可以通過(guò)PCR,由釀酒酵母基因組DNA的起始密碼子ATG開(kāi)始直到并包括終止密碼子來(lái)擴(kuò)增必需基因。用于此目的的引物,可以用以下方式構(gòu)建,使得它們包含適當(dāng)限制酶的識(shí)別位點(diǎn),并有利于隨后插入后表達(dá)載體中可調(diào)節(jié)啟動(dòng)子的控制之下。
含有在可調(diào)節(jié)啟動(dòng)子控制之下的釀酒酵母必需基因質(zhì)??截惖闹亟M表達(dá)載體,隨后被用于相應(yīng)突變等位基因的反式互補(bǔ)。相應(yīng)突變等位基因可從雜合子二倍體突變株中選出,這些雜合子二倍體突變株是通過(guò)同源重組而部分或全部缺失以上所列舉并描述的真菌必需基因所得到的。
含有選定釀酒酵母必需基因的表達(dá)載體,被轉(zhuǎn)化到相應(yīng)的雜合子二倍體突變株中,該突變株攜帶有選擇標(biāo)記基因,而不攜帶選定的釀酒酵母必需基因。轉(zhuǎn)化體通過(guò)所用表達(dá)載體中的營(yíng)養(yǎng)缺陷型標(biāo)記選擇分離。經(jīng)轉(zhuǎn)化的雜合子二倍體突變株隨后進(jìn)行四分體分析。可以得到四個(gè)存活的分離子。通過(guò)反向追蹤突變等位基因和表達(dá)載體的相應(yīng)標(biāo)記,轉(zhuǎn)化的野生型分離子可以與不含有必需基因基因組拷貝的分離子區(qū)分開(kāi)。不含有選定必需基因基因組拷貝的分離子,被指定為反式互補(bǔ)單倍體突變株。它們隨后被合適載體中的其它真菌的cDNA文庫(kù)或者基因組DNA文庫(kù)轉(zhuǎn)化。
誘導(dǎo)型啟動(dòng)子或阻抑型啟動(dòng)子可以用作可調(diào)節(jié)啟動(dòng)子。這些啟動(dòng)子可以由天然和/或人工排列的啟動(dòng)子序列組成。
例如,GAL1基因的啟動(dòng)子和相應(yīng)的啟動(dòng)子衍生物,比如缺失不同UAS(上游激活序列)元件的啟動(dòng)子(GALS,GALL;Mumberg,J.等(1994)核酸研究225767-5768),可以用作可調(diào)節(jié)啟動(dòng)子。糖元異生基因的啟動(dòng)子,例如FBP1,PCK1,ICL1或者它們的部分,比如它們的激活序列(UAS1和/或UAS2)或者阻抑序列(URS,上游阻抑序列)(Niederacher等(1992),Curr.Genet.22636-670;Proft等(1995)Mol.Gen.Gent.246367-373;Schller等(1992)EMBOJ;11107-114;Guarente等(1984)細(xì)胞36503-511),也可以用作可調(diào)節(jié)啟動(dòng)子。
以這種方式修飾的釀酒酵母突變株,可以在可調(diào)節(jié)啟動(dòng)子被激活的生長(zhǎng)環(huán)境中培養(yǎng),使得釀酒酵母必需基因得以表達(dá)。接著,用含有所研究真菌cDNA或者基因組DNA的典型數(shù)量的文庫(kù)轉(zhuǎn)化釀酒酵母細(xì)胞。轉(zhuǎn)化子將表達(dá)額外的蛋白質(zhì),這些蛋白質(zhì)的編碼序列存在于重組載體中。
本方法希望,為了抑制控制著選定必需基因的可調(diào)節(jié)啟動(dòng)子,生長(zhǎng)條件可以進(jìn)行修改。特別是,可以通過(guò)更換生長(zhǎng)培養(yǎng)基來(lái)改變生長(zhǎng)條件。例如,當(dāng)使用GAL1啟動(dòng)子或其衍生物時(shí),可以用含葡萄糖的培養(yǎng)基(抑制狀態(tài))替換含半乳糖的培養(yǎng)基(誘導(dǎo)狀態(tài))。
對(duì)于其重組載體中不含有所研究真菌的功能相似基因組DNA或cDNA的釀酒酵母細(xì)胞,這種經(jīng)過(guò)修改的條件是致命的。相反的,其重組載體表達(dá)所研究真菌的功能相似編碼序列的釀酒酵母細(xì)胞可以存活,因?yàn)樵谶@些細(xì)胞中,功能相似基因編碼的蛋白質(zhì)彌補(bǔ)了致命的代謝缺陷。
本方法希望,使用已知的方法(Strathern,J.N.和Higgins,D.R.(1991).Plasmids are recovered from yeast into Escherichiacoli shuttle vectors inGuthrie,C.and Fink,G.R.酶學(xué)方法,Volume 194.酵母遺傳學(xué)和分子生物學(xué)指南.Academic Press,SanDiego,319-929)從存活的轉(zhuǎn)化子中分離重組載體(質(zhì)粒),使用象是DNA測(cè)序(Singer等(1997),Proc.Natl.Acad.Sci.USA745463-5467)這樣的DNA分析方法來(lái)分析cDNA和基因組DNA。
這樣,釀酒酵母必需基因就可以用于鑒定其它病原體真菌中的功能相似基因和/或序列同源基因,特別是鑒定人類、動(dòng)物、植物的病原體真菌中的功能相似必需基因和/或序列同源必需基因。為此,可以使用例如藻狀菌綱或者真菌綱的真菌,特別是擔(dān)子菌(basidiomycetes)亞綱,子囊菌(ascomycetes)亞綱,尤其是mehiascomycetales(酵母)和plectascales(霉菌)和gymnascales(皮膚和毛發(fā)真菌),或者h(yuǎn)yphomycetes綱的真菌,特別是conidiosporales亞綱(皮膚真菌)和thallosporales亞綱(芽殖或出芽真菌),尤其是毛霉菌屬(mucor),根霉屬(rhizopus),球孢子菌屬(coccidioides),副球孢子菌屬(paracoccidioides)巴西芽生菌(blastomyces brasiliensis),內(nèi)孢霉屬(endomyces)(芽生菌屬),曲霉屬(aspergillus),青霉屬(penicilium),毛癬菌屬(trichophyton(ctenomyces)),帚霉屬(表皮癬菌屬),小孢子菌屬(microsporon),毛孢子菌屬(piedraia),單孢枝霉屬(hormodendron),瓶霉屬(phialophora),孢子絲菌屬(sporotrichon),隱球酵母屬(cryptococcus),念珠菌屬(candida),地霉屬(geotrichum)和絲孢酵母屬(trichosporon)。
特別感興趣的是使用以下真菌,念珠菌屬的種(Candida Spp.),特別是白色念珠菌(Candida Albicans),Candida glabrata,曲霉屬的種(Aspergillus Spp.),特別是煙曲霉(Aspergillusfumigatus),粗球孢菌(Coccidioides immitis),新型隱球酵母(Cryptococcus neoformans),莢膜組織胞漿菌(Histoplasmacapsulatum),皮炎芽生菌(Blastomyces dermatitidis),Paracoccidioides brasiliens和Sporotrix schenckii。
從根據(jù)上述方法鑒定的釀酒酵母基因開(kāi)始,申請(qǐng)人使用以下方法從白色念珠菌中克隆出了相應(yīng)必需基因,即CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或者CaJL039。
首先,為了擴(kuò)增白色念珠菌的相應(yīng)片段,從釀酒酵母基因序列或者白色念珠菌同源序列中選擇寡核苷酸??寺≈?,所得片段(序列長(zhǎng)度大約為幾百bp)被用作探針篩選白色念珠菌(基因組)DNA文庫(kù)。篩選可以包括下面幾步把克隆涂布到平皿上,用交聯(lián)有DNA的濾紙覆蓋,與濾紙雜交,檢測(cè)出陽(yáng)性克隆。對(duì)選出的克隆進(jìn)行測(cè)序。
本方法希望,用真菌必需基因鑒定可以部分或者全部抑制這些必需基因的功能表達(dá)和/或編碼蛋白的功能活性的物質(zhì)??梢杂眠@種方式鑒定這些物質(zhì),這些物質(zhì)可以抑制真菌生長(zhǎng),并可用作抗真菌劑,例如用于制備藥物。
本發(fā)明特別包括一種篩選這種抑制物質(zhì)的方法,其中選自CaOR110,CaMR212,CaNL256,CaBR102,CaIR012,CaDR325或者CaJL039的白色念珠菌必需基因或者其它病原體真菌的功能相似基因,或者相應(yīng)編碼蛋白質(zhì)被用作靶。
其它病原體真菌的功能相似基因,是指與已鑒定的白色念珠菌必需基因功能相似或一致的基因。其它病原體真菌的功能相似基因,可以但不必與相應(yīng)的白色念珠菌必需基因序列同源。其它病原體真菌的功能相似基因,在核酸水平上,可以只表現(xiàn)出與相應(yīng)的白色念珠菌必需基因中等程度的序列同源性。中等程度的序列同源性,在本發(fā)明中是指,在核苷酸水平上要有至少50%的序列同一性,優(yōu)選有至少60%的序列同一性,最優(yōu)選有至少70%的序列同一性。
另外,其它病原體真菌中的功能相似基因,可以但不是必須編碼與白色念珠菌必需基因編碼的蛋白質(zhì)序列同源的蛋白質(zhì)。其它真菌中的功能相似蛋白質(zhì),可以只表現(xiàn)出與白色念珠菌必需基因編碼的蛋白質(zhì)中等程度的蛋白質(zhì)序列同源性。
中等程度的蛋白質(zhì)序列同源性,在本發(fā)明中是指,在氨基酸水平上要有至少40%的序列同一性,優(yōu)選有至少50%的序列同一性,更優(yōu)選有至少60%的序列同一性,最優(yōu)選有至少70%的序列同一性。
本方法的一個(gè)特征是,使用真菌必需基因或者相應(yīng)的編碼蛋白質(zhì)作為靶來(lái)篩選物質(zhì)。本方法希望,白色念珠菌必需基因,以及其它病原體真菌的功能相似基因和/或序列同源基因,或者相應(yīng)的編碼蛋白質(zhì),可以用作靶。
根據(jù)本發(fā)明篩選方法的一種實(shí)施方案,要提供含有用作靶的必需基因的真菌細(xì)胞,并將其與被測(cè)物質(zhì)一同保溫。用這種方法來(lái)測(cè)定這種物質(zhì)對(duì)于必需靶基因的生長(zhǎng)抑制效果。
使用以不同程度表達(dá)必需靶基因的真菌細(xì)胞,將這些細(xì)胞與被測(cè)物質(zhì)一同保溫,測(cè)定這種物質(zhì)的生長(zhǎng)抑制效果。
本方法包括,使用兩種或兩種以上的真菌細(xì)胞,或其衍生菌株,衍生菌株的不同在于,它們表達(dá)必需靶基因的程度不同。
例如,對(duì)于二種、三種、四種、五種、十種或者更多的真菌細(xì)胞或者相應(yīng)的真菌菌株,可以比較分析被測(cè)物質(zhì)在測(cè)定濃度下對(duì)它們的生長(zhǎng)抑制效果??拐婢镔|(zhì)可以通過(guò)這種表達(dá)程度系列與細(xì)胞毒性物質(zhì)或者非活性物質(zhì)區(qū)分開(kāi)。
本方法的一種特殊實(shí)施方案,包括使用單倍體真菌細(xì)胞/菌株進(jìn)行篩選,特別是單倍體釀酒酵母細(xì)胞/菌株。
本方法希望,選作靶的必需基因要整合到合適的表達(dá)載體中。
例如,大腸桿菌/釀酒酵母穿梭載體是一種合適的表達(dá)載體。尤其是可以使用在每個(gè)細(xì)胞中拷貝數(shù)不同的載體。所以,可以使用在經(jīng)轉(zhuǎn)化的釀酒酵母細(xì)胞中有高拷貝數(shù)的載體,也可以使用低拷貝數(shù)的載體。一種實(shí)施方案,包括使用允許把靶基因整合到釀酒酵母基因組中去的表達(dá)載體。
例如,載體pRS423,pRS424,pRS425,pRS426,pRS313,pRS314,pRS315,pRS316,pRS303,pRS304,pRS305,pRS306(Sijkorski和Hieter,1989;Christianson等1992)適合作為表達(dá)載體。
pRS423-pRS426系列載體具有高拷貝數(shù),大約50-100拷貝/細(xì)胞。相反的,pRS313-pRS316系列載體具有低拷貝數(shù)(1-2拷貝/細(xì)胞)。當(dāng)使用這兩個(gè)系列的表達(dá)載體時(shí),靶基因以染色體外拷貝形式出現(xiàn)。使用pRS303-pRS306系列載體,可以把靶基因整合到基因組中。使用這三種不同類型的表達(dá)載體,可以逐步表達(dá)所研究的功能相似必需基因。
本方法包括,通過(guò)使用例如單細(xì)胞中拷貝數(shù)不同的表達(dá)載體,來(lái)比較測(cè)定物質(zhì)對(duì)于真菌細(xì)胞/菌株的生長(zhǎng)抑制效果。
這種細(xì)胞可以以不同程度表達(dá)必需的靶基因,并且可以對(duì)所說(shuō)的物質(zhì)發(fā)生逐步的反應(yīng)。
本方法也包括,通過(guò)在表達(dá)載體上的所選釀酒酵母特殊啟動(dòng)子和終止子之間插入靶基因,可以在不同真菌細(xì)胞中得到目的基因不同強(qiáng)度的表達(dá)。(可調(diào)控的過(guò)量表達(dá))以不同強(qiáng)度組成型表達(dá)的釀酒酵母啟動(dòng)子是合適的。這種啟動(dòng)子的實(shí)例有,釀酒酵母基因MET25,PGK1,TPI1,TDH3,ADHI,URA3,TRP1的天然啟動(dòng)子,以及它們的相應(yīng)衍生物,例如沒(méi)有特殊激活序列和/或阻抑序列的啟動(dòng)子衍生物。
可調(diào)節(jié)啟動(dòng)子也適合用于靶基因的逐漸過(guò)量表達(dá)。GAL1基因的天然啟動(dòng)子和/或其相應(yīng)衍生物,例如已經(jīng)缺失了不同UAS元件的啟動(dòng)子(GALS,GALL;Mumberg等(1994)核酸研究225767-5768),以及糖元異生基因的啟動(dòng)子,例如啟動(dòng)子FBP1,PCK1,ICL1或其部分,比如它們的激活(UAS1或UAS2)序列或者阻抑(URS)序列,可以用于相應(yīng)的非激活和/或非阻抑試驗(yàn)啟動(dòng)子(Schüller等(1992)EMBO J;11107-114;)Guarente等(1984)細(xì)胞36503-511;Niederacher等(1992)Curr.Genet.22363-370;Proft等(1995)Mol.Gen.Gent.246367-373;)。
例如釀酒酵母基因MET25,PGK1,TPI1,TDH3,ADHI,URA3的終止子序列,可以用作表達(dá)載體的終止子。
本方法包括,通過(guò)靈巧地使用所選類型的表達(dá)載體和/或制備合適的表達(dá)載體,并最終使用不同強(qiáng)度或者受不同調(diào)控的啟動(dòng)子,可以構(gòu)建一系列表達(dá)載體,這些表達(dá)載體都含有相同的靶基因,但是它們表達(dá)靶基因的程度不同。
本方法包括,在釀酒酵母單倍體野生型細(xì)胞中表達(dá)載體的轉(zhuǎn)化。這樣得到的釀酒酵母細(xì)胞/菌株,在含有不同濃度被測(cè)物質(zhì)的液體培養(yǎng)基中進(jìn)行培養(yǎng),比較分析這種物質(zhì)對(duì)于以不同程度表達(dá)靶基因的細(xì)胞/菌株的生長(zhǎng)行為的效果。本方法也包括,將經(jīng)各種不含有靶基因的表達(dá)載體轉(zhuǎn)化的釀酒酵母單倍體細(xì)胞/菌株,用作對(duì)照。
本方法包括,使用可調(diào)節(jié)啟動(dòng)子,特別是GAL1啟動(dòng)子及其衍生物(GALS和GALL)在不同的培養(yǎng)基中進(jìn)行所說(shuō)物質(zhì)的篩選,因?yàn)楦鞣N培養(yǎng)基的選擇在很大程度上影響表達(dá)的程度。因此,GAL1啟動(dòng)子的表達(dá)程度以下述方式減少2%半乳糖>1%半乳糖+1%葡萄糖>2%甘油>2%葡萄糖。
該物質(zhì)抑制釀酒酵母野生型細(xì)胞生長(zhǎng)的作用,可以通過(guò)其它真菌的功能相似基因的過(guò)量表達(dá)得以部分或者全部的彌補(bǔ)。
根據(jù)一種實(shí)施方案,篩選抗真菌物質(zhì)的方法在體外進(jìn)行,將必需基因或者功能相似基因,或者相應(yīng)編碼蛋白質(zhì),與被測(cè)試物質(zhì)接觸,并且測(cè)定該物質(zhì)對(duì)靶的效果??梢允褂萌魏斡糜诖_定兩個(gè)分子相互作用的體外試驗(yàn),例如雜交試驗(yàn)或者功能試驗(yàn)(例如,Bergmeyer H.U.,酶分析法,VCH Publishers中所述的酶促試驗(yàn))。如果使用編碼蛋白質(zhì)作為靶進(jìn)行篩選,相應(yīng)必需基因通過(guò)本領(lǐng)域已知的任何合適的技術(shù),例如使用一套含有合適限制性酶切位點(diǎn)的引物的PCR擴(kuò)增,(最新分子生物學(xué)方法,John Wiley和Sons,Inc),被插入到表達(dá)系統(tǒng)中,例如大腸桿菌,桿狀病毒或者酵母,然后用本領(lǐng)域已知的方法完全或部分地純化表達(dá)蛋白質(zhì)。任何合適的純化表達(dá)蛋白質(zhì)的純化方法都可以使用,例如親和層析。如果靶蛋白功能已知,那么可以進(jìn)行功能試驗(yàn)測(cè)定抗真菌物質(zhì)對(duì)蛋白質(zhì)功能的效果。如果靶蛋白功能未知,可以測(cè)定與靶蛋白相互作用的物質(zhì),例如結(jié)合到編碼蛋白質(zhì)上的物質(zhì)。在這種情況下,可以進(jìn)行諸如保護(hù)蛋白質(zhì)不被合適的酶酶解這樣的試驗(yàn)。
根據(jù)一種具體的實(shí)施方案,篩選抗真菌物質(zhì)的方法相當(dāng)于一種酶促分析,其中要測(cè)定二氫蝶酸合酶(DHPS)和/或7,8-二氫-6-羥甲基蝶呤-焦磷酸激酶(HPPK)的活性;酶促分析可以象在“BergmeyerH.U.,酶分析法,VCH Publishers”中公開(kāi)的那樣。
二氫蝶酸合酶(DHPS)催化6-羥甲基-7,8-二氫蝶呤焦磷酸與對(duì)-氨基苯甲酸縮合,形成7,8-二氫蝶酸,這與從6-羥甲基-7,8-二氫蝶呤產(chǎn)生7,8-二氫葉酸的三步途徑的第二步一致。7,8-二氫-6-羥甲基蝶呤-焦磷酸激酶(HPPK)催化焦磷酸結(jié)合到6-羥甲基-7,8-二氫蝶呤上,形成6-羥甲基-7,8-二氫蝶呤焦磷酸,這與產(chǎn)生7,8-二氫葉酸的三步途徑的第一步一致。所有的生物體都需要還原葉酸輔因子,以合成各種代謝物。大多數(shù)微生物必須從頭合成葉酸,因?yàn)樗鼈內(nèi)鄙俑叩燃棺祫?dòng)物細(xì)胞的活性轉(zhuǎn)運(yùn)系統(tǒng),這種活性轉(zhuǎn)運(yùn)系統(tǒng)使得這些高等生物可以使用食物中的葉酸。所以,與葉酸生物合成相關(guān)的酶也就成為各種抗微生物藥劑的靶。因此,這種酶活性對(duì)于微生物是必需的,而人體中并不存在。
本方法也包括鑒定與來(lái)自人類、動(dòng)物或者植物的白色念珠菌的必需基因功能相似和/或序列同源的基因。在本方法中,相應(yīng)的人類、動(dòng)物或者植物的基因,可以選擇性地用作靶基因,以檢測(cè)抗真菌物質(zhì)對(duì)于這些靶基因是否有作用。
本方法的一個(gè)特殊優(yōu)點(diǎn)是,以這種方式,可以鑒定出有效抑制真菌生長(zhǎng)的物質(zhì),也可以確定這些物質(zhì)對(duì)來(lái)自人類、動(dòng)物或者植物的白色念珠菌必需基因相應(yīng)的功能相似基因和/或序列同源基因的影響。
本方法也包括,例如通過(guò)檢驗(yàn)已確定的真菌必需基因或其部分與數(shù)據(jù)庫(kù)中提供的人類、動(dòng)物或者植物基因序列的同源性。來(lái)檢驗(yàn)人類、動(dòng)物或者植物中與相應(yīng)真菌必需基因功能相似的基因和/或序列同源基因存在的可能性,用這種方法,根據(jù)目的,可以在早期就從已鑒定真菌必需基因中篩選出特定基因,例如與人類基因沒(méi)有功能相似和/或序列同源的基因。
因此,本方法提供了多種選擇性鑒定具有抗真菌效果而對(duì)人體無(wú)害的物質(zhì)的可能性。
例如,可能鑒定出一些物質(zhì),這些物質(zhì)可以用于制備治療真菌病藥劑或者制備在免疫抑制狀態(tài)下進(jìn)行預(yù)防的藥劑。
例如,這些物質(zhì)可以用于生產(chǎn)用于治療真菌感染的藥劑,真菌感染常在諸如艾滋病或者糖尿病等疾病發(fā)生期間發(fā)生。也可以鑒定可用于生產(chǎn)殺真菌劑的物質(zhì),特別是對(duì)人類和動(dòng)物無(wú)害的殺真菌劑。
另外,本方法提供了鑒定抗真菌物質(zhì)的可能性,這些抗真菌物質(zhì)可以選擇性地只抑制特殊真菌的生長(zhǎng)。
本篩選方法具有特殊的優(yōu)點(diǎn),因?yàn)橥ㄟ^(guò)這種方法可以充分識(shí)別基因是否是必需的,而不需要與必需基因功能有關(guān)或者與其編碼蛋白的功能有關(guān)的多余信息。另外,其它真菌的許多這種基因的DNA序列尚未獲得,其中的與釀酒酵母必需基因功能相似基因的鑒定便具有特殊的優(yōu)越性。
