Abstract
本发明提供了一类提高苹果酸产量的新突变蛋白。具体地,本发明提供了一类新的丙酮酸羧化酶突变蛋白和苹果酸转运蛋白突变蛋白或其组合,以及其制备方法以及在提高苹果酸产量中的应用。
Description
技术领域
本发明属于生物技术领域,具体地,本发明涉及苹果酸合成途径中的丙酮酸羧化酶以及苹果酸转运蛋白的新的突变蛋白及其应用。
背景技术
苹果酸(2-羟基-1,4-丁二酸)是一种重要的平台化合物,被广泛应用于药物、化妆品、食品及饮料行业。以往的合成主要是采用化学的方法,然而该过程产生的主要是D、L-苹果酸的混合物,很难分离。
苹果酸合成目前报道的主要有5条途径,分别是TCA循环,还原型TCA(或者反向TCA)rTCA,环形乙醛酸循环和非环形乙醛酸循环,及依赖于苹果酸酶反向催化丙酮酸直接合成苹果酸。其中以rTCA循环和苹果酸酶途径最为有效,其葡萄糖对苹果酸的理论转换率为2,然而苹果酸酶主要催化苹果酸分解为丙酮酸,因此,目前最常用的方法是rTCA途径来合成苹果酸。
从葡萄糖出发经过糖酵解转化为丙酮酸,丙酮酸经过丙酮酸羧化酶转变为草酰乙酸,草酰乙酸经过苹果脱氢酶转化为苹果酸,苹果酸经过转运蛋白运出细胞。该过程中每一步的转化效率,副反应分流,催化每一步反应的辅酶和还原力及细胞能量状态都会对苹果酸合成造成影响。
苹果酸合成中有三个关键的指标,分别是产量,生产能力和转化率。为了构建高效的苹果酸生产菌株,人们在多个物种中构建了苹果酸的合成途径,如酿酒酵母(Saccharomyces cerevisiae)、毕赤酵母(Pichia pastoris)、大肠杆菌(Escherichiacoli)、曲霉属(Aspergillus spp.)、光滑球拟酵母(Torulopsis glabrata)、稗草黑粉病菌(Ustilago trichophora)、枯草芽孢杆菌(Bacillus subtilis)和嗜热子囊菌(Thermobifida fusca)等(Dai et al.,Current advance in biological production ofmalic acid using wild type and metabolic engineered strains.BioresourTechnol.2018,258:345-353.Liu et al.,Biological production of L-malate:recentadvances and future prospects.World J Microbiol Biotechnol.2017,34(1):6.)。然而这些工作主要是在不同物种中尝试构建苹果酸合成途径及进行部分优化,如选用不同强度的启动子表达苹果酸合成中的关键酶来提升苹果酸合成能力,然而这需要一个多轮组合过程且过量表达合成关键酶也会对细胞造成额外的负担。
因此,本领域迫切需要开发一种能够直接高效获得纯的苹果酸的方法。

具体实施方式
本发明人通过广泛而深入的研究,首次意外地发现,针对对苹果酸合成的催化机器及转运蛋白进行改造,即对丙酮酸羧化酶和苹果酸转运蛋白特定位点的核心氨基酸进行突变后,微生物菌株生产苹果酸的能力具有显著提高,从而能够使更多的丙酮酸前体流向目标产物苹果酸,从而有效地提高苹果酸产量。具体地,本发明人首先在毕赤酵母中构建了苹果酸合成偶联的高通量筛选方案,对不同来源的丙酮酸羧化酶、苹果酸转运蛋白进行了比较,找到要改造的目标蛋白,对两个目标蛋白分别构建随机突变文库,多次筛选后获得苹果酸产量提升的丙酮酸羧化酶和苹果酸转运蛋白突变体,然后进行单氨基酸饱和突变和组合突变,获得了催化活性提高的丙酮酸羧化酶突变体和苹果酸转运能力提升的苹果酸转运蛋白突变体,并构建了一系列高效合成苹果酸的工程菌株。在此基础上,完成了本发明。

苹果酸合成目前报道的主要有5条途径,分别是TCA循环,还原型TCA(或者反向TCA)rTCA,环形乙醛酸循环和非环形乙醛酸循环,及依赖于苹果酸酶反向催化丙酮酸直接合成苹果酸。其中以rTCA循环和苹果酸酶途径最为有效,其葡萄糖对苹果酸的理论转换率为2,然而苹果酸酶主要催化苹果酸分解为丙酮酸,因此,目前最常用的方法是rTCA途径来合成苹果酸。

以往的合成主要是采用化学的方法,然而该过程产生的主要是D、L-苹果酸的混合物,很难分离。而本发明采用微生物的方法则可以合成高纯度的L-苹果酸。
丙酮酸羧化酶
丙酮酸羧化酶(Pyruvate carboxylase,PYC)是生物体内参与中心代谢途径的关键酶之一,通过羧化丙酮酸形成草酰乙酸参与到TCA循环中,同时这步反应也是糖异生途径的第一步反应。大多数丙酮酸羧化酶都由四个相同的亚基组成,单个亚基的分子量为120-130kDa,其发挥功能的四聚体分子量约520kDa。于丙酮酸羧化酶需要四聚化才能发挥功能,该四聚化后的蛋白有520kDa之多,难以分泌到细胞外,虽然丙酮酸羧化酶可以通过测定酶活的方法进行筛选,然而其只能驻留胞内,需要破碎细胞才能进行酶活测定,若对一个突变库中所有突变体进行破壁处理很难实施,造成了该蛋白改造起来难度很大。目前针对这类形成复合体的蛋白改造也只有极少数基于晶体结构基础上针对特定位点的定点突变,所涉及到的突变体非常之少,而对没有晶体结构的CgPYC则没有进行过蛋白质工程改造。
本发明的丙酮酸羧化酶来源于谷氨酸棒杆菌(Corynebacterium glutamicum)其野生型(命名为CgPYC)序列号为WP_011013816.1,序列如SEQ ID NO:1所示,其编码核酸如SEQ ID NO:21所示。是首次被用于苹果酸合成的菌株中。通过构建随机突变,定点突变和组合突变,获得多个可以显著提升毕赤酵母苹果酸合成30%以上的单点突变和2个提升苹果酸40%以上的双突变和三突变,同时,突变蛋白在嗜热毁丝霉中也可提高苹果酸16%。
苹果酸转运蛋白
苹果酸转运蛋白在苹果酸合成过程中发挥着重要作用,本发明用于苹果酸生产的转运蛋白主要有来源于米曲霉Aspergillus oryzae(AO090023000318(C4T318)),野生型(命名为AoMae)的蛋白序列如SEQ ID NO:22所示,其编码核酸如SEQ ID NO:43所示;来源于Schizosaccharomyces pombe的(NM_001020205.2)和来源于Aspergillus carbonarius的DCT(AQW79505.1),其中关键的AoMae蛋白理论分子量42.2kDa。
苹果酸转运蛋白Aomae属于膜蛋白,膜蛋白通常的评价标准是对底物转运能力进行测定,需要将蛋白纯化出来,构建于脂质体中,或者构建于一个没有类似功能转运蛋白的多基因敲除菌株中,然后通过同位素标记的底物进行测定;此外,转运又分为外排型和内运型,加之膜蛋白的蛋白一致性一般较低,这些因素都给改造膜蛋白造成了非常大的困难。
本发明经过随机突变,定点突变和组合突变,获得了一系列突变位点可以显著提高苹果酸合成水平,其中I80K/E8Q/R272A和I80K/R272A可提升毕赤酵母苹果酸合成30%以上,在嗜热毁丝霉中也可提升苹果酸10.5%。

三、基于水解圈的高通量筛选方法构建:由于20-30g/L的苹果酸钙可溶的特性(本研究前期发现),我们建立了水解圈的高通量筛选方法。具体方法是:当转运蛋白表达质粒转入P0感受态细胞,待长出菌落后,以无菌牙签将菌落挑取,然后穿刺于产苹果酸的固体培养基(液体中加入2.0g/L琼脂,CaCO3的浓度为3g/L),每天检查水解圈的大小,以水解圈的直径与菌落直径的比值作为筛选标准,值越大,说明产苹果酸越高。
四、Aomae突变文库构建及产苹果酸突变株筛选:对来源于A.oryzae的AoMae进行蛋白质工程改造,以AoMae-BstBI和AoMae-NotI为引物,采用随机突变试剂盒GeneMorph IIRandom Mutagenesis(Agilent)进行AoMae的随机突变扩增,将PCR产物采用BstBI和NotI酶切后与pGAP-hph-his进行连接,连接产物转化大肠杆菌感受态细胞DH5α,涂布于含有125μg/ml潮霉素的LB固体平板培养基,37℃过夜培养,随机挑取20个单克隆进行测序,分析突变率,结果表明突变率在1%左右。对突变库用含有125μg/ml潮霉素的LB液体培养基洗脱下来,然后37℃复苏2h,后提取混合质粒,经过AvrII线性化后转化P0感受态细胞,涂布于MD平板,待长出单菌落后,穿刺于产苹果酸固体培养基,以AoMae野生型菌株P1为对照,突变库中比P1水解圈大的菌株(图8),通过摇瓶进行复筛和HPLC苹果酸含量测定。

而后经过玻璃纸过滤后,2000rpm 4℃离心10min,弃上清,加入4mL溶液B(0,735g氯化钙,18,22g山梨醇,1ml Tris HCl 1M pH 7.5,溶于90ml去离子水,盐酸调PH到7.6,定量至100ml,高温灭菌),2000rpm 4℃离心10min;弃上清,按200μl/质粒加入一定体积溶液B。
3)原生质体转化
预冷的15ml离心管,依次加入50ul预冷PEG(12.5g PEG6000,0,368g氯化钙,500μlTris HCl 1M pH 7.5。),10μl用HindIII线性化的质粒,200μl原生质体。放置冰上20min后加入2ml预冷PEG,室温5min,加入4mL溶液B,轻轻混匀。取3ml上述溶液加入12ml融化的含相应抗生素MM培养基中,置于平板中,45℃培养,2d-4d后于体式显微镜下挑取单个菌丝体于相应抗性平板生长,而后用PCR进行验证。
三、嗜热毁丝霉转化子生产苹果酸能力测定
将上述验证的转化子全部接种至250ml三角瓶中的50mL以结晶纤维素(Avicel)为碳源培养基中(配方:碳源75g/l,蛋白胨6.0g/l,0.15g/l KH2PO4,0.15g/l K2HPO4,0.10g/lCaCl2·2H2O,0.10g/l MgSO4·7H2O,碳酸钙80.0g/l,1mL/L 0.5g/l生物素,1ml/l微量元素液;微量元素配方(100ml):5g C6H8O·7H2O,5g ZnSO4·7H2O,1g Fe(NH4)2(SO4)·6H2O,0.25g CuSO4·5H2O,0.05g MnSO4·H2O,0.05g H3BO3,0.05g NaMoO4·2H2O,溶于水中,定容至100ml),接种量为2.5*105个/ml,45℃,150rpm培养,第八天取样测定苹果酸含量。
1)样品处理:
取1ml发酵液于15ml离心管中,并添加1ml 1M H2SO4,而后80℃下放置30min,每个隔10min进行充分震荡。之后将2ml双蒸水添加至离心管中,充分震荡后,取1ml液体于1.5ml离心管中,12000rpm离心10min,取上清液测定苹果酸含量。
2)苹果酸含量测定
处理后的样品用高效液相色谱测定苹果酸含量,其中检测器为紫外检测器,5mMH2SO4为流动相,流速为0.5ml/min。结果显示苹果酸转运蛋白经过改造后,相比野生型转运蛋白,能显著促进苹果酸的生产。第八天时,转化子MaeKA的苹果酸产量为46g/l,相比对照菌株WtMae(42g/l)提高9.5%。实验说明C4-二羧酸转运蛋白经过改造后,能够显著提高嗜热真菌嗜热毁丝霉苹果酸生产能力。
