Abstract
本发明公开了一种生产L‑谷氨酸的方法。本发明通过定向进化的方法获得了谷氨酸外运能力提高的外运变体,并提供了一种生产L‑谷氨酸的方法,包括如下步骤:在受体菌中表达所述谷氨酸外运蛋白变体,得到重组菌;对所述重组菌进行发酵培养,从发酵液中获得谷氨酸。本发明为丰富谷氨酸外运的理解及提高生产中谷氨酸的产量奠定了基础。
Description
技术领域
本发明涉及基因工程技术领域,具体涉及一种生产L-谷氨酸的方法。
背景技术
谷氨酸棒杆菌的历史始于20世纪50年代,当时日本科学家Kinoshita和Udaka分离出这种细菌并发现了它们分泌大量谷氨酸的能力。后来,用细菌发酵来生产谷氨酸,从而完全用生物过程取代化学合成。随后,该细菌不断被科学家研究,并利用其独特的生理学特性来改善谷氨酸的生产。此外,谷氨酸棒杆菌现已成为生产各种氨基酸的工业主力菌。在氨基酸市场中,广泛用作增味剂的L-谷氨酸市场规模巨大,每年生产总量约250万吨,占氨基酸生产总量的60%-70%左右。因此,研究如何提高谷氨酸的产量是十分必要的。
但近年来随着分子生物学的快速发展,分子生物学技术在谷氨酸研究领域的应用越来越广泛,大量谷氨酸发酵的机理被不断揭示。发现负责谷氨酸外运是由外运蛋白负责的,如:mscCG基因编码的外运蛋白。目前对于这类外运蛋白的研究较少,未发现通过突变提高其转运能力的文献。所以,通过对外运蛋白进行基因改造,筛选出外运谷氨酸能力较强的L-谷氨酸棒杆菌菌株,从而提高谷氨酸产量是非常有必要的。
发明内容
为了克服现有技术的不足,本发明的目的是提供一种外运能力提高的谷氨酸外运蛋白变体及其编码基因和相关应用。

具体实施方式
下述实施例中所使用的实验方法如无特殊说明,均为常规方法。
下述实施例中所用的材料、试剂等,如无特殊说明,均可从商业途径得到。
实施例1、谷氨酸外运蛋白的基因克隆
从谷氨酸棒杆菌的基因组中克隆出MscCG谷氨酸外运蛋白目的基因,基因序列如SEQ ID NO.12所示,然后连接到pTRCmob载体中,测序确定载体构建成功得到重组质粒,命名为pTRCmob-MscCG。
pTRCmob-MscCG的结构描述为:将SEQ ID NO.12所示DNA片段克隆到pTRCmob载体的酶切位点SacI和BamHI之间后得到的重组质粒。SEQ ID NO.12为野生型MscCG谷氨酸外运蛋白目的基因,编码SEQ ID NO.1所示的野生型MscCG谷氨酸外运蛋白。
实施例2、外运能力提高的谷氨酸外运蛋白突变体筛选
为了提高上述谷氨酸外运蛋白外运能力,以实施例1中构建得到的重组质粒pTRCmob-MscCG为模板,设计引物(上游引物:5′-ATGATTTTAGGCGTACCCAT-3′;下游引物:5′-CTAAGGGGTGGACGTCGGCG-3′),加入Mn2+用PCR的方法对目的基因进行随机突变。将突变产物电转到谷氨酸棒杆菌感受态细胞中,30℃过夜培养得到重组菌之后,将长出的单克隆分别用无菌牙签接种到96孔板中(含有150μl LBG培养基,25mg/ml Kana),30℃、800rpm摇床培养45h后检测谷氨酸的产量。对检测结果进行分析,最终筛选出10株谷氨酸外运量提高的突变菌株,分别命名为M1、M2、M3、M4、M5、M6、M7、M8、M9、M10。
对上述各突变菌株进行基因测序,其具体的突变氨基酸位点,以及突变后的具体氨基酸序列和基因序列详见表1。
表1突变氨基酸位点
注:表中的氨基酸取代,使用下述命名法:原始氨基酸(野生型),位置(即在SEQ IDNo.1中的位置),取代氨基酸。相应地,在SEQ ID No.1的第166位用丙氨酸取代原有的苏氨酸氨酸命名为“T166A”。
实施例3、谷氨酸外运蛋白及其外运变体在谷氨酸棒杆菌中的表达
接种环刮取野生型和实施例2获得的表1中所示10个突变体的阳性菌接种于10mLCGXII种子培养基中,以30℃、220rpm在恒温培养摇床(上海知楚仪器有限公司,上海,中国)培养12h,然后以起始OD600为0.15的接种量分别接种于25ml CGXII发酵培养基和50mlCGXII发酵培养基中(接种到500ml的锥形瓶中),以30℃、220rpm在恒温培养摇床(上海知楚仪器有限公司,上海,中国)培养。培养38h后离心收集发酵液,用SBA-40D生物传感分析仪(山东省科学院生物研究所,山东,中国)测发酵液中L-谷氨酸的产量。
其中,CGXII种子培养基的溶剂为水,溶质及浓度如下:5g/L葡萄糖,20g/L硫酸铵,5g/L尿素,1g/L磷酸二氢钾,1.3g/L磷酸氢二钾,80g/L MOPS,0.01g/L氯化钙,0.25g/L硫酸镁,0.01g/L硫酸亚铁,0.01g/L硫酸锰,0.001g/L硫酸锌,0.2mg/L硫酸铜,0.02mg/L氯化镍,0.03g/L二羟基苯甲酸,2.5μg/L生物素,0.1mg/L Thiamine HCL VB1。
CGXII发酵培养基的溶剂为水,溶质及浓度如下:80g/L葡萄糖,20g/L硫酸铵,5g/L尿素,1g/L磷酸二氢钾,1.3g/L磷酸氢二钾,80g/L MOPS,0.01g/L氯化钙,0.25g/L硫酸镁,0.01g/L硫酸亚铁,0.01g/L硫酸锰,0.001g/L硫酸锌,0.2mg/L硫酸铜,0.02mg/L氯化镍,0.03g/L二羟基苯甲酸,1μg/L生物素,0.1mg/L Thiamine HCL VB1。
检测结果如图1、图2、图3所示。图1是在25ml CGXII发酵培养基中培养的,结果表明外运变体M2、M6、M7、M10谷氨酸的产量分别比野生型谷氨酸的产量高33.3%、37.5%、33.3%、25%。图2是在50ml CGXII发酵培养基中培养的,结果表明外运变体M5、M8、M9谷氨酸的产量分别是野生型谷氨酸产量的4.4倍、6.6倍、5.2倍。图3是在50ml CGXII发酵培养基中培养的,结果表明外运变体M1、M3、M4、谷氨酸的产量分别比野生型谷氨酸的产量高50%、50%、25%。
