甘油脱水酶是微生物发酵法生产3-羟基丙醛和1,3-丙二醇过程中的关键限速酶.文中对甘油脱水酶的结构与功能、作用机制、基因工程研究等情况进行综述,探讨了甘油脱水酶的研究进展并提出一些建议.
Glycerol dehydratase(GDHt) is a key rate-limiting enzyme in the process of producing 3-hydroxypropionaldehyde(3-HPA) and 1,3-propanediol(1,3-PD) by microbial fermentation.In this paper,the research in the structure and functions,catalytic mechanism and genetic engineering of GDHt were reviewed.The research progresses of GDHt were also discussed and some suggestions were given in the end.
