Chemical logic of MraY inhibition by antibacterial nucleoside natural products

Abstract

Phospho-MurNAc-pentapeptide translocase (MraY) is a bacterial integral membrane enzyme that is essential for peptidoglycan biosynthesis. Here the authors present the crystal structures of MraY from Aquifex aeolicus bound to caprazamycin, capuramycin and mureidomycin and discuss the implications for antibiotic development.
