Crystal structure of MltF from Pseudomonas aeruginosa complexed with bulgecin and muropeptide

Released:
Source organism: Pseudomonas aeruginosa PAO1
Entry authors: Redden E, Thunnissen AMWH

Function and Biology Details

Reaction catalysed:
Exolytic cleavage of the (1->4)-beta-glycosidic linkage between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc) residues in peptidoglycan, from either the reducing or the non-reducing ends of the peptidoglycan chains, with concomitant formation of a 1,6-anhydrobond in the MurNAc residue.
