技術(shù)領(lǐng)域
本發(fā)明涉及利用微生物通過融合蛋白的表達(dá)而生產(chǎn)多肽。更具體地,本發(fā)明涉及一種能改進(jìn)融合蛋白的生產(chǎn)的細(xì)胞,所述融合蛋白包含與外源多肽融合的天然果膠酸裂解酶,本發(fā)明還涉及產(chǎn)生所述融合蛋白和/或所述多肽的方法。
背景技術(shù)
蛋白質(zhì)或多肽目前通過多種方式進(jìn)行工業(yè)化生產(chǎn),所有方式均涉及能產(chǎn)生該蛋白質(zhì)的微生物的培養(yǎng)。多種使蛋白質(zhì)的工業(yè)化產(chǎn)量最佳化的方法為本領(lǐng)域已知,并已常規(guī)應(yīng)用,如對(duì)培養(yǎng)基進(jìn)行操作,通過例如突變來改變微生物,使諸如啟動(dòng)子和信號(hào)序列等能影響編碼所需蛋白的基因表達(dá)的遺傳元件發(fā)生變異,以及對(duì)基因本身進(jìn)行操作以便例如增強(qiáng)蛋白質(zhì)的穩(wěn)定性或提高活性。
融合蛋白已被描述為生產(chǎn)用其它方法難以獲得的蛋白質(zhì)的一種途徑,這些蛋白質(zhì)如活性人類抗體(Goshorn,S.C.等,癌癥研究,(1993)第53卷(9),第2123-2127頁)。

發(fā)明詳述細(xì)胞本發(fā)明的細(xì)胞優(yōu)選革蘭氏陽性細(xì)胞,更優(yōu)選芽孢桿菌細(xì)胞,甚至更優(yōu)選選自下組的細(xì)胞地衣芽孢桿菌(Bacillus licheniformis)、Bacillus clausii、短芽孢桿菌(Bacillus brevis)、解淀粉芽孢桿菌(Bacillus amyloliguefacienss)、枯草芽孢桿菌(Bacillus subtilis)、遲緩芽孢桿菌(Bacillus lentus)、嗜熱脂肪芽孢桿菌(Bacillus stearothermophilus)、嗜堿芽孢桿菌(Bacillus alkalophilus)、凝固芽孢桿菌(Bacillus coagulans)、環(huán)狀芽孢桿菌(Bacillus circulans)、燦爛芽孢桿菌(Bacillus lautus)、蘇云金芽孢桿菌(Bacillus thuringiensis)、和Bacillusagaradhaerens。
果膠酸裂解酶由本發(fā)明的方法產(chǎn)生的、作為融合蛋白一部分的果膠酸裂解酶優(yōu)選選自以下果膠酸裂解酶,它們含有選自SEQ ID 2,SEQ ID 4,SEQ ID 6,SEQ ID8,SEQ ID 10的氨基酸序列,和具有與SEQ ID 2,SEQ ID 4,SEQ ID 6,SEQID 8和SEQ ID 10中任何一個(gè)至少70%的氨基酸序列相似性的氨基酸序列。
示于SEQ ID 2(其相應(yīng)DNA序列示于SEQ ID 1)并已證實(shí)十分有利于天然酶所結(jié)合的多肽異源表達(dá)的果膠酸裂解酶與其它四種果膠酸裂解酶密切相關(guān)。
那四種果膠酸裂解酶的完整DNA序列示于SEQ ID 3,SEQ ID 5,SEQID 7,和SEQ ID 9。它們?cè)诖俗鳛榭捎米魅诤吓鋵?duì)物以便在芽孢桿菌細(xì)胞中表達(dá)外源多肽的其它果膠酸序列的實(shí)例。這些序列公開在WO 99/27084中。
可將果膠酸裂解酶蛋白序列最小化至某種程度而仍維持其在融合蛋白表達(dá)中使用時(shí)的有利特性。這種對(duì)DNA序列以及因此對(duì)所編碼的蛋白質(zhì)序列的最小化可通過分子生物學(xué)領(lǐng)域已知的任何方法實(shí)現(xiàn)。
其中一個(gè)方法是,設(shè)計(jì)特異性PCR引物,通過PCR構(gòu)建與目標(biāo)蛋白融合的果膠酸裂解酶的截短形式,并檢驗(yàn)這種新構(gòu)建體的表達(dá)水平。這類構(gòu)建體可缺失果膠酸裂解酶C末端的一部分,果膠酸裂解酶N末端的一部分,或二種末端都缺失。另一種方法是,用內(nèi)切核酸酶處理果膠酸裂解酶編碼序列,使得編碼果膠酸裂解酶C末端的部分被降解至各種程度。攜與目標(biāo)肽融合之果膠酸裂解酶的不同長度N末端部分的克隆組成一個(gè)文庫,可在該文庫中以鑒定最佳表達(dá)構(gòu)建體的方式篩選這些克隆的表達(dá)能力。該方法也可應(yīng)用于果膠酸裂解酶融合構(gòu)建體,使得果膠酸裂解酶N末端的部分或N末端及C末端均缺失,從而使融合蛋白得到最佳表達(dá)。
酶解位點(diǎn)在本發(fā)明的一個(gè)優(yōu)選實(shí)施方案中,用于蛋白酶剪切的靶位點(diǎn)是由蛋白酶識(shí)別并裂解的氨基酸序列。
