摘要:

磷酸-N-乙酰胞壁酸酯-胸腺喷丁转位酶(MraY, 转位酶I)是细菌中普遍存在且对细菌生长有重要作用的一种酶, 发展新的抗菌药物的重要靶点。此外, 几类此酶的抑制剂已经被发现。近来, MraY的晶体结构也被Chung等阐明。结合晶体结构及其抑制剂的构效关系研究将有助于活性药效团的确定和对作用机制的深入了解。本文概述了MraY的整体结构及其抑制剂, 并对这些抑制剂的构效关系和MraY作为抗菌药物靶点的前景进行了讨论。

Abstract:

The phospho-murNAc-pentapeptide translocase (MraY, translocase I) is a good target for the development of new antibiotics as it is ubiquitous and essential for bacterial growth. Furthermore, several inhibitors targeting towards this enzyme have been discovered. Recently, the crystal structure of MraY has been presented by Chung et al. Combination of the crystal structure and structure-activity relationship studies on these inhibitors could lead to the identification of active pharmacophores, and insight into their mechanisms of action. In this review, we described the structure and inhibitors of MraY. In addition, we also discussed the structure-activity relationship of these inhibitors and prospects of MraY as an antibacterial target.

Key words: Peptidoglycan, MraY, Antibiotic, Structure-activity relationships
