Protein attributes

Sequence length	165 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Essential for lysis of bacterial cell wall, by showing cell wall hydrolyzing activity. Acts as a transglycosylase By similarity.
Catalytic activity	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.
Sequence similarities	Belongs to the glycosyl hydrolase 24 family.
