葡萄糖基转移酶的结构、功能及应用研究进展

Research Progress in Structures,Functions,and Applications of Glucanotransferases

淀粉的消化性能与机体的健康相关,而酶法改性可显著提升淀粉的抗消化性能,促进机体健康。葡萄糖基转移酶作为近些年被发现的酶类,具有改性淀粉的能力,可用于制备新型可溶性、慢消化的产物,在淀粉改性领域具有广阔的应用前景。该文从葡萄糖基转移酶的来源与酶学性质、结构与进化、催化机理及应用的研究现状进行概述,为葡萄糖基转移酶的深入研究及利用其开发新型功能性食品提供参考。

The digestibility of starch directly affects human health.Enzymatic modification significantly im⁃proves the anti⁃digestibility of starch,which benefits human health.Glucanotransferases,as novel enzymes discovered recently,are able to convert starch into new soluble,slowly digestible products,demonstrating a promising prospect in starch modification.The origins,enzymatic properties,structures,evolution,mecha⁃nisms,and applications of glucanotransferases were introduced,which provided a theoretical basis for further research on glucanotransferases and their applications in the development of new functional food products.
