Membrane-bound lytic murein transglycosylase A homolog

Gene

mltA

Organism
Buchnera aphidicola subsp. Schizaphis graminum (strain Sg)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Murein-degrading enzyme. May play a role in recycling of muropeptides during cell elongation and/or cell division (By similarity).By similarity

Catalytic activityi

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.
