蛋白酶的生产和应用(上)

Proteases Production and its application (The first part)

为充分了解蛋白酶,该文从蛋白酶的分类与底物专一性、微生物蛋白酶的生产等方面介绍了蛋白酶。蛋白酶按活性中心可分为丝氨酸蛋白酶、天门冬氨酸蛋白酶、半胱氨酸蛋白酶和金属蛋白酶;按最适pH值来分又分酸性蛋白酶、中性蛋白酶和碱性蛋白酶。微生物蛋白酶的产生与微生物生长有关,合成受分解代谢阻遏的调控和底物及其类似物的诱导,并介绍了生产蛋白酶的微生物。

In order to make a full appreciation of protease, this article introduces its classification, substrate specificity,and the production of microorganism protease. According to its active center, protease can be divided into Serine, Aspartic Acid protease, β -Mercapto alanlne protease and metal protease. According to its optimal pH degree, protease can be classified as acidic protease, neutral protease, and alkaline protease. Microorganism＇s growth affects greatly microorganism protease. Catabolism controls microorganism protease＇s combination, which is also induced by substrate and other similar matter. Relative microorganism is introduced as well in the article.
