General annotation (Comments)

Function

Plays an important role in cell wall degradation and cell separation By similarity.

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.

Subcellular location

Secreted By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 73 family.

Contains 13 cell wall-binding repeats.
