Protein name

RecName: Full=Putative O-sialoglycoprotein endopeptidase; Short=Glycoprotease; EC=3.4.24.57;

Gene name

gcp

CATALYTIC ACTIVITY: Hydrolysis of O-sialoglycoproteins; cleaves 31-Arg-|-Asp-32 bond in glycophorin A. Does not cleave unglycosylated proteins, desialylated glycoproteins or glycoproteins that are only N-glycosylated.

COFACTOR: Zinc (By similarity).

SIMILARITY: Belongs to the peptidase M22 family.
