Protein attributes

Sequence length	880 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Cell wall hydrolase not involved in cell autolysis. It hydrolyzes the beta-1,4 glycan bond between the N-acetylglucosaminyl and the N-acetylmuramoyl residues in the glycan chain.
Catalytic activity	Endohydrolysis of the N,N'-diacetylchitobiosyl unit in high-mannose glycopeptides and glycoproteins containing the -(Man(GlcNAc)2)Asn-structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact.
Subunit structure	Homodimer.
Subcellular location	Secreted.
Sequence similarities	Belongs to the glycosyl hydrolase 73 family.
