O-sialoglycoprotein endopeptidase (EC 3.4.24.57, glycoprotease, glycophorin A proteinase, glycoproteinase, sialoglycoprotease, sialoglycoproteinase, "OSGE") is an enzyme.[1][2][3] 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-glycosylated
This enzyme is secreted by the bacterium Pasteurella haemolytica.
