角质酶的研究进展

Advances in cutinase research

摘要:

角质酶(EC 3.1.1.74)是一种可以降解角质并产生大量脂肪酸单体的水解酶。角质酶是一种多功能酶, 可水解可溶性酯、不溶性甘油三酯和各种聚酯, 同时还能催化酸与醇的酯化、脂肪酸盐与醇的转酯化反应, 因此在食品工业、化工工业等诸多领域都具有广泛的应用。近年来研究发现, 角质酶可实现棉纤维的生物精练和合成纤维的生物改性, 是推动纺织工业清洁生产的关键酶制剂。

Abstract:

Cutinase (EC 3.1.1.74) is a kind of hydrolase capable of catalyzing the cleavage of ester bonds of cutin to release fatty acids. Cutinase displayed hydrolytic activity not only toward cutin but also a variety of soluble synthetic esters, insoluble triglycerides and polyesters. Besides its hydrolytic activity, cutinase also showed synthetic activity and transester activity. Therefore, cutinase was evaluated as a versatile lipolytic enzyme used in food and chemical industry. Recently, it is found that cutinase has potential use in cotton bio-scouring and synthetic fibers modification. Cutinase is the most important enzyme in clean production of textile industry.
