EC 220.127.116.11 - O-sialoglycoprotein endopeptidase
IntEnz Enzyme Nomenclature
- 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.
An enzyme secreted by the bacterium Pasteurella haemolytica. Inhibited by EDTA (100 mM) and 1,10-phenanthroline. Type example of peptidase family M22.
