IUBMB Enzyme Nomenclature


Accepted name: pancreatic endopeptidase E

Reaction: Preferential cleavage: Ala. Does not hydrolyse elastin

Other names: cholesterol-binding proteinase; proteinase E; cholesterol-binding serine proteinase; pancreatic protease E; pancreatic proteinase E; cholesterol-binding pancreatic proteinase; CBPP; pancreas E proteinase

Comments: A peptidase of family S1 (trypsin family) from pancreatic juice. Unlike elastases, has an acidic pI. Binds cholesterol
