微生物NAD合成酶及其抑制剂的研究进展

Microbial NAD synthetase and its inhibitors - A review

摘要:

摘要：NAD(P)生物代谢在能量代谢,维持氧化还原稳态以及调节细胞寿命等许多细胞进程中有重要作用。因此,NAD生物合成途径的关键酶的抑制剂就成为备受关注的候选新药，如NAD合成酶抑制剂。本文对微生物中的NAD合成酶的催化活性特征，晶体结构,调控因子以及基于晶体结构的抑制剂设计方面进行了综述,以期为基于NAD的治疗领域打开新的思路。

Abstract:

Abstract: Nicotinamide - adenine dinucleotide (phosphate) (NAD(P)) metabolism involves many fundamental cellular events, such as energy metabolism, maintenance of redox homeostasis and regulation of cell longevity. Inhibitors of essential enzymes of NAD(P) biosynthetic pathways might be promising leads for novel antibiotics, such as the NAD synthase inhibitors. This review described the crystal structural, functional properties, regulator and structure-based inhibitors design for NAD synthase. This might provide the basis for developing NAD-based therapeutics.
