catalytic Activity CATALYTIC ACTIVITY: Reaction=Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins.; EC=3.2.1.17; Evidence={ECO:0000269|PubMed:17021237};
DNA Binding
EC Number 3.4.22.-; 3.2.1.17
Enzyme Function FUNCTION: The endopeptidase activity cleaves the bacterial peptidoglycan between D-alanine and L-alanine (PubMed:15256551, PubMed:17021237). The N-acetyl-muramidase activity cleaves between N-acetylmuramic acid and N-acetylglucosamine bonds (PubMed:17021237). {ECO:0000269|PubMed:15256551, ECO:0000269|PubMed:17021237}.
