Description

谷氨酸脱氢酶突变体及其在制备L-草铵膦中的应用
技术领域
本发明涉及酶工程技术领域，尤其涉及谷氨酸脱氢酶突变体及其在制备L-草铵膦中的应用。
技术背景
草铵膦(4-[羟基(甲基)膦酰基]-DL-高丙氨酸)是一类含磷的氨基酸类除草剂，作用的靶标是谷氨酰胺合成酶，具有活性高、吸收好、杀草谱广、低毒、环境兼容性好等特点。近些年，作为世界第三大非灭生性除草剂及世界第二大转基因作物耐受除草剂，草铵膦表现出巨大的市场潜力，主要的促因是抗草铵膦转基因农作物的大范围推广及其主要竞品(草甘膦与百草枯)市场的萎缩。
草铵膦的两种构型中，只有L-型具有除草活性，而市售的草铵膦均为其消旋体(Herbicidal compositions[P].Patent application US4265654 A，1981)。L-型草铵膦单体的使用，能够显著减少草铵膦的施用量，减轻环境的压力，同时减缓杂草抗性的产生，表现出非常显著的环保优势。
因此，L-草铵膦制备工艺的开发具有非常重要的意义。在实验室规模下，已经有多条酶法制备L-草铵膦的工艺被开发出来，其中一条比较有潜力的就是利用谷氨酸脱氢酶氨化还原2-羰基-4-(羟基甲基膦酰基)丁酸(PPO)制备L-草铵膦(生物法合成L-草铵膦的研究进展[J],《现代农药》,2009,8(3):1-4.)。
谷氨酸脱氢酶(Glutamate dehydrogenase,EC 1.4.1.2–1.4.1.4)是一类能够可逆的将谷氨酸氧化脱氨生成α-酮戊二酸的氧化还原酶，在生物体内几乎无所不在。根据其辅酶特异性，可将其分为NADH依赖型、NADPH依赖型及NADH/NADPH双辅酶依赖型的谷氨酸脱氢酶。微生物通常会表达NADH依赖型或NADPH依赖型的谷氨酸脱氢酶其中的一种，植物则会在线粒体和叶绿体中分别表达NADH依赖型和NADPH依赖型的谷氨酸脱氢酶，而动物细胞中表达的均为NAD(P)双辅酶依赖型的谷氨酸脱氢酶(The biochemistry and enzymology ofamino acid dehydrogenases[J].Critical reviews in biochemistry and molecularbiology,1994,29(6):415-467.)。与转氨酶等酶法制备L-草铵膦工艺相比，利用谷氨酸脱氢酶氨化还原PPO制备L-草铵膦具有两个显著的优点：1)当辅酶再生系统效率较高时，底物能够实现100％的转化；2)利用无机铵作为氨基供体，无难分离副产物的产生，产物易于提纯精制。
在公布号为CN106978453A的发明专利中，本团队利用基于基因组挖掘的酶库构建策略，获得多株对PPO具有催化活力的谷氨酸脱氢酶，并成功将其应用于L-草铵膦的氨化还原制备，这些谷氨酸脱氢酶的获得证明了该工艺的可行性。但是，从实际应用的角度来讲，这些谷氨酸脱氢酶的酶活均较低，其中酶活最高的谷氨酸脱氢酶重组菌其单位发酵液的酶活也仅为35.54U/L。较低的酶活会带来催化剂制备成本过高、后处理困难等一系列问题。因此，能否提高谷氨酸脱氢酶对PPO的催化活力是该工艺能否实现工业应用的关键。
另外，上述发明专利中获得的对PPO具有催化活力的谷氨酸脱氢酶均为NADPH依赖型，在以NADH为辅酶时并无催化活性。而相对于NADP(H)，NAD(H)的使用无论是在稳定性还是成本方面都具有显著优势。因此，如果能开发对PPO具有催化活力的NADH依赖型的谷氨酸脱氢酶，就可实现L-草铵膦生产成本的近一步降低。
发明内容
本发明针对还原胺化法制备L-草铵膦工艺中谷氨酸脱氢酶酶活低及缺乏对PPO具有催化活力的NADH依赖型谷氨酸脱氢酶的问题，通过对谷氨酸脱氢酶底物结合口袋处的氨基酸进行定点突变，获得了一类在催化底物2-羰基-4-(羟基甲基膦酰基)丁酸或其盐制备L-草铵膦工艺中具有高酶活的NADPH依赖型谷氨酸脱氢酶突变体或者对PPO具有催化活力的NADH依赖型谷氨酸脱氢酶突变体，显著提高了底物转化率和产物L-草铵膦的浓度。

实施例1 Pseudomonas putida来源的谷氨酸脱氢酶的改造及活力测定
步骤一：重组菌的活化及质粒提取
将带有编码Pseudomonas putida来源的谷氨酸脱氢酶(NCBI登录号：NP_742836.1)基因的大肠杆菌工程菌(PpGluDH)使用LB培养基进行活化与培养。
LB培养基的具体配方为：蛋白胨10g/L，酵母粉5g/L，NaCl 10g/L，用去离子水溶解后定容，121℃灭菌20min，待用。固体培养基为LB培养基加入2％的琼脂。
将保存有PpGluDH工程菌的甘油管划线至含有LB固体培养基的平皿上，37℃静置培养12h。从平皿上挑取单菌落接入含50μg/mL卡那霉素的5mL LB培养基中，37℃、200rpm培养12h。在获得培养液后，根据质粒提取试剂盒的操作说明书进行质粒的提取。所得质粒可直接用于后续操作也可置于-20℃长期保存。
步骤二：定点突变
设计特异性引物(见表1)，分别将PpGluDH氨基酸序列中167位的丙氨酸突变为甘氨酸(A167G)，378位的缬氨酸突变为丙氨酸(V378A)。
表1 PpGluDH定点突变引物
注：带下划线的密码子编码突变后的氨基酸
以步骤一中提取的质粒为模版，利用Quickchange技术(An efficient one-stepsite-directed and site-saturation mutagenesis protocol[J].Nucleic AcidsResearch,2004,32(14):e115)引入突变，PCR反应体系和反应条件如下：
PCR扩增体系：
PCR扩增条件：
1)预变性：98℃2min；
2)变性：98℃15s；退火：58℃10s；延伸：72℃2min；共循环30次；
3)后延伸：72℃10min；
4)4℃保存。
PCR扩增结束后，扩增产物用DpnⅠ消化3h去除模版质粒，消化产物转化至E.coliBL21(DE3)感受态细胞中，涂平板、挑单菌落至LB液体培养，测序验证突变正确性。验证后无误的阳性突变性置于-80℃保藏备用。
步骤三：菌体的培养及粗酶液的制备
将保藏的工程菌在经平皿划线活化后，挑单菌落接种至含50μg/mL卡那霉素的5mLLB液体培养基中，37℃震荡培养12h。按2％的接种量转接至50mL同样含50μg/ml卡那霉素的新鲜LB液体培养基中，37℃震荡培养至OD600达到0.6左右时，加入IPTG至其终浓度为0.5mM，18℃下诱导培养16h。
培养结束后，将培养液10000rpm离心10min，弃上清，收集菌体。将培养结束后收集到的菌体，用50mM pH 7.5的磷酸盐缓冲液洗涤菌体两次。之后将菌体重悬于pH 7.5的磷酸盐缓冲液中，400W功率超声破碎30次，每次超声持续3s，间歇7s。将此细胞破碎液12000g 4℃离心5min去除沉淀，得到的上清为含重组谷氨酸脱氢酶的粗酶液。
步骤四：酶活的测定
标准酶活检测体系：适量的酶、100mM底物、10mM辅酶(NADH或NADPH)、500mM NH4 +((NH4)2SO4)，总体系为400μL，反应介质为pH 7.5磷酸盐缓冲液。35℃反应10min,反应结束后加入40uL 5M NaOH终止反应。
酶活的定义：在标准的反应条件下，每分钟生成1μmol L-草铵膦所需要的酶量。
按照上述酶活测定方法，测定了PpGluDH野生型及利用上述改造策略改造后的突变株PpGluDH-A167G，PpGluDH-V378A单位体积发酵液的酶活。PpGluDH野生型的酶活为0.11U/mL，PpGluDH-A167G的活力为14.85U/mL，较野生型提高了135倍；PpGluDH-V378A的活力为13.3U/mL，较野生型提高了121倍。
同时，也测定了纯化获得的纯酶(附图6)的比酶活。经测定，PpGluDH野生型纯蛋白的比酶活为0.31U/mg；A167G的比酶活为38.13U/mg，较野生型提高了123倍；V378A的活力比酶活为35.96U/mg，较野生型提高了116倍。
步骤五：组合突变株构建及酶活的测定
将构建好的PpGluDH-A167G突变株按步骤一进行活化及质粒提取，再利用V378A-F/V378A-R这对引物进行全质粒PCR进行突变，具体方法见步骤二，构建了PpGluDH-A167G/V378A组合突变株(SEQ ID NO.22)。按步骤三、四对该组合突变株进行了诱导培养并测定了其酶活。经测定，PpGluDH-A167G/VA78A的活力单位体积发酵液为13.85U/mL，较野生型提高了126倍。
对比例1
分光光度法测定了PpGluDH野生型及突变株对其它酮酸底物的催化活力。相对于野生型，突变株对大部分的底物(2-8a，10-11a，13a)都表现出催化活力的降低。对于2-酮戊二酸(1a)及2-酮己酸(9a)，PpGluDH-A167G及PpGluDH-V378A均表现出催化活力的提高，而对于高苯丙酮酸(12a)，PpGluDH-A167G的催化活力有所提高，而PpGluDH-V378A的催化活力则有所下降。

实施例2
步骤一：谷氨酸脱氢酶的选择
选取9个不同来源、不同辅酶特异性及与PpGluDH具有不同同源性的谷氨酸脱氢酶进行同样的蛋白质的改造(详细信息见表2)。其中CgGluDH、PeGluDH、LsGluDHp为NADPH依赖型的谷氨酸脱氢酶，GsGluDH、BsGluDH、BmGluDH、LsGluDH、CsGluDH、BtGluDH为NADH依赖型谷氨酸脱氢酶。
表2待拓展谷氨酸脱氢酶
注：同源性比较以PpGluDH的氨基酸序列作为参考。
步骤二：对应突变点的选择及突变体的构建
通过在线软件T-Coffee(http://tcoffee.vital-it.ch/apps/tcoffee/do:regular)进行多序列比对，找到各谷氨酸脱氢酶与PpGluDH的A167及V378相对应的氨基酸残基(附图7)。
通过比对结果可以发现，不同的谷氨酸脱氢酶其与PpGluDH对应的这两个氨基酸残基均为丙氨酸与缬氨酸，表明这两个氨基酸残基非常保守。将这些谷氨酸脱氢酶的这两个氨基酸残基均突变成甘氨酸与丙氨酸，详细的突变株见表3。按实施例一中的步骤一、二进行突变体的构建。
表3谷氨酸脱氢酶待构建突变株
步骤三：突变体的构建及酶活的测定
将构建好的突变株进行诱导表达培养，并制备粗酶液。通过标准酶活测定体系测定了这些突变株对PPO的催化活力，结果如表4所示。
表4分子改造策略拓展突变株酶活检测结果
从酶活测定的结果可以看出，对于NADPH依赖性谷氨酸脱氢酶，无论是167位(以PpGluDH氨基酸序列编码)还是378位(以PpGluDH氨基酸序列编码)的突变株酶活均较野生型显著提高，最高的提高倍数达1641。
对于NADH依赖型的谷氨酸脱氢酶，其167位(以PpGluDH氨基酸序列编码)的突变株均从野生型的没有酶活获得了较为可观的酶活。
