Description
技术领域
本发明涉及一种提高蛋白质谷氨酰胺酶分泌表达的方法,属于基因工程技术领域。
背景技术
蛋白质谷氨酰胺酶(protein-glutaminase,EC3.5.1.44,简称PG)是一类特异性谷氨酰胺脱酰胺水解酶。蛋白质谷氨酰胺酶主要应用于食品工业,大量研究验证该酶能显著改善小麦谷蛋白、米谷蛋白等植物蛋白的溶解度、乳化性和起泡性等功能,蛋白质谷氨酰胺酶的脱酰胺作用不需要提前对蛋白质进行预处理且特异性强,只作用于蛋白质的侧链的谷氨酰胺,对天冬酰胺无脱酰胺作用,且不会对蛋白质的结构造成不良变化。但是目前蛋白质谷氨酰胺酶的应用受到制约,其中蛋白分泌表达量低是其中一个重要因素。
与产蛋白质谷氨酰胺酶的野生解朊金黄杆菌相比,枯草芽孢杆菌作为传统的工业生产菌,具有极强的蛋白质分泌能力,是蛋白质谷氨酰胺酶表达和分泌的良好系统。目前研究表明枯草芽孢杆菌的启动子与信号肽等表达元件的选择与优化对外源蛋白表达有重要影响。其中,信号肽最主要功能就是引导分泌蛋白或膜蛋白,在细胞内不同区域或不同细胞器进行正确定位,可提高外源蛋白质的可溶性,避免因包涵体复性带来的产物纯化等困难。然而信号肽对蛋白的表达分泌往往具有特异性,同一种蛋白质在不同信号肽的作用下,表达分泌效率往往相差甚远,缺乏普适应的规律。
因此,获得高效、特异性的信号肽序列,改善蛋白质谷氨酰胺酶蛋白分泌途径,提高蛋白质谷氨酰胺酶表达效率,是很有难度的事情,但具有重要的应用价值。
