Description
技术领域
本发明涉及一种耐金属离子和有机溶剂的羧酸酯酶及其应用,属于酶工程领域。
背景技术
羧酸酯酶(carboxylesterase,EC 3.1.1.1)是指能够催化水解羧酸酯生成羧酸和醇的非特异性酯酶。羧酸酯酶在生产和实际生活中应用广泛,并且已经得到了越来越多现代药物工业、手性化合物合成以及精细化工等相关行业的青睐。利用羧酸酯酶作为催化剂催化手性分子合成,例如生产萘普生和2-芳基萘酸;同时羧酸酯酶也被作为绿色催化剂降解土壤中的农药残留及土壤、水体中的塑化剂邻苯二甲酸酯类。由于产自动植物的羧酸酯酶存在着酶活低、产量少、提取复杂、热稳定性差等缺陷,而微生物来源的羧酸酯酶具有良好的区位选择性和立体选择性,可以高效温和的催化酯类和酰胺类化合物的水解、酯合成和酯交换等反应,在食品工业、生物去污剂、医药、能源开发和环境保护等相关领域都具有广阔的应用前景。
微生物中羧酸酯酶存在于真菌、细菌及个别种类的放线菌中。真菌在其中承担着重要作用,真菌中12属23种可产生羧酸酯酶;由于真菌来源的羧酸酯酶表达量少、酶活较低,而细菌来源的羧酸酯酶容易获得,酶学性质优异,催化效率高,所以细菌来源的羧酸酯酶越来越受到人们的关注。在细菌中羧酸酯酶主要存在于包括链球菌、乳杆菌、假单胞菌中。而野生菌中羧酸酯酶的表达量较低,不能满足工业应用;随着基因工程应用于羧酸酯酶的研究中,很多羧酸酯酶基因得到了异源表达。
但目前大部分羧酸酯酶对于金属离子和有机溶剂的耐受性较低,严重限制了羧酸酯酶的应用。例如谢振荣等人从脂环酸芽孢杆菌中克隆得到的羧酸酯酶CarE3和CarE5在1mM的不同金属离子Cu2+,Zn2+,Ag+,Fe3+中放置1h后,剩余的相对酶活均小于15%;将其放置于不同有机溶剂乙醇、甲醇、异丙醇和丙酮中放置1h后,酶活分别降低了28%、45%、70%和49%。Chenghong Wang等人从废水杆菌属中克隆得到的羧酸酯酶,当其在10mM不同金属离子中放置1h后,Zn2+,Ca2+,Fe3+对酶活性有轻度的抑制作用,而NH4 +,Mg2+,Cu2+,Ag+严重抑制的酶的活性。Nehad Noby等人从极端微生物中克隆出的酯酶EstN7,当其在5mM的不同金属离子中,酶活性受到Cu2+,Zn2+,Ca2+,Na+金属离子不同程度的抑制作用。
且由于羧酸酯酶的大部分底物都是难溶于水的,耐有机溶剂的羧酸酯酶可以在含有有机溶剂的缓冲液(代替水相缓冲液)中更好的作用于底物,因此,获得一种既耐金属离子又耐有机溶剂的羧酸酯酶,在工业应用中将具有十分重要的价值和意义。
