微生物糖苷水解酶19家族几丁质酶的研究进展

Advances in microbial glycoside hydrolases family 19 chitinases

摘要:

几丁质是地球上储量仅次于纤维素的第二大可再生资源。几丁质酶是降解几丁质的关键酶类。糖苷水解酶19家族(glycoside hydrolases family 19, GH19)几丁质酶主要存在于高等植物中。近年来，来自微生物的GH19几丁质酶被广泛发现。本文从分布、结构特征、酶学性质及应用等方面综述了微生物来源GH19几丁质酶的研究进展，并对未来的研究方向进行了展望。

Abstract:

Chitin is the second largest renewable resource only after cellulose on Earth. Chitinases are the key enzymes for degrading chitin. Chitinases of the glycoside hydrolase family 19 (GH19) mainly exist in higher plants. In recent years, microbial GH19 chitinases have been widely discovered. This paper reviews the research progress in microbial GH19 chitinases regarding their distribution, structures, enzymatic properties, and applications and prospects the research directions in the future.
