Protein attributes

Sequence length	184 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Involved in both cell wall peptidoglycans recycling and beta-lactamase induction. Specifically cleaves the amide bond between the lactyl group of N-acetylmuramic acid and the alpha-amino group of the L-alanine in degradation products containing an anhydro N-acetylmuramyl moiety By similarity.
Catalytic activity	Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
Cofactor	Zinc; required for amidase activity By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.
