γ-谷氨酰转肽酶催化特性研究进展OACSCD

γ-Glutamyl transpeptidase(GGT)widely exists in a variety of organisms in nature,has transpeptidation and hydrolysis activities,and can synthesize γ-glutamyl amino acids/polypeptides according to different substrate conditions.Substances have attracted the attention of the food industry,pharmaceutical synthesis and other industries because they can be used as flavor enhancers or biological actives.There are abundant GGT resources in bacteria.In this paper,the structural characteristics,properties,catalytic reaction characteristics and related product characteristics of γ-glutamyl transpeptidase were reviewed in order to explore the potential of bacterial GGT and provided reference for future research prospects.
