(a) The structure of muraymycins. (b) Conformation of muraymycin D2 (1d, green color) in the 1d-bound MraY structure (PDB: 5CKR). The hydrogen bond, water–hydrogen bond, π–π stacking interaction, and salt bridge interaction between 1d and MraY are shown in green, cyan, magenta, and orange dashed lines, respectively. Water molecules are presented as red spheres.
