摘　　要：胰蛋白酶广泛存在于各类动物体内,是动物生长发育中不可缺少的一类催化蛋白质水解的酶.作为动物细胞内重要的水解酶,胰蛋白酶在自身活化以及激活胰分泌的其它蛋白酶类方面起关键作用,一般认为胰蛋白酶的活性与其结构和特性紧密相关.对近年来国内外主要动物胰蛋白酶的作用机理、基因、酶蛋白的氨基酸组成、结构及重组胰蛋白酶的表达等最新研究进展进行了综述,并展望了胰蛋白酶今后的研究发展方向.Trypsin exists widely in all kinds of animal cells.It is an indispensable enzyme for protein hydrolysis in animal growth and development.As an important digestive enzyme,the trypsin plays critical role in activating of itself and other proteases secreted by pancreas.It is generally thought that the activity of trypsin is concerned with its structure and properties.According to the recent research reports on trypsin worldwide,reviewed research advances on the animal trypsin,involving its catalytic mechanisms,gene,protein structure,catalytic properties,as well as the expression of recombinant trypsin.Furthermore,the prospect was suggested on its exploitation and utilization.
