摘要:

GH79家族的糖苷水解酶在碳水化合物改性、细胞免疫识别和信号传导等方面具有广泛的生理活性和重要的应用前景。然而,目前GH79家族的多样性催化机理仍不清楚,识别底物的结构基础和分子机制尚不清晰。本文总结了近几年GH79家族的研究进展,系统分析了GH79家族酶的来源与分布,通过对酶的序列特征、分子进化关系、蛋白结构解析等方面进行深入阐述,旨在为后续的GH79家族的蛋白质工程和功能催化机制的解析奠定基础。

Abstract:

The glycoside hydrolases of the GH79 family have extensive physiological activities and important application prospects in carbohydrate modification, cellular immune recognition and signal transduction. However, the diverse catalysis mechanism of GH79 family remains unclear, and the structural basis and molecular mechanism of substrate recognition are still unclear. This review summarizes the research progress of the GH79 family, systematically analyzes the origin and distribution of GH79 family enzymes, and deeply expounds their sequence features, molecular evolutionary relationships, and the crystal structures analysis, aiming to lay a foundation for protein engineering and functional metabolic mechanism of GH79 family.

Key words: GH family 79, catalytic mechanism, molecular evolution, structural analysis
