O-sialoglycoprotein endopeptidase (EC 3.4.24.57 glycoprotease glycophorin A proteinase glycoproteinase sialoglycoprotease sialoglycoproteinase) is an enzyme. This enzyme catalyses the following chemical reaction Hydrolysis of O-sialoglycoproteins; cleaves -Arg31-Asp- bond in glycophorin A. Does not cleave unglycosylated proteins desialylated glycoproteins or glycoproteins that are only N-glycosylatedThis enzyme is secreted by the bacterium Pasteurella haemolytica.
