Schematic structure of peptidoglycan and MDP. PGN, a major component of the bacterial cell membrane, is a crystal lattice structure formed by the combination of linear chains of two alternating amino sugars, GlcNAc and MurNAc. MDP consists of MurNAc and two amino acids, L-Ala and D-Glu. M: MurNAc; G: GluNAc.
