Magnolysin
Magnolysin (, bovine neurosecretory granule protease cleaving pro-oxytocin/neurophysin, pro-oxytocin/neurophysin convertase, prooxyphysin proteinase, pro-oxytocin convertase) is an enzyme. This enzyme catalyses the following chemical reaction
Hydrolysis of polypeptides with Arg or Lys in P1 and P2, e.g. to hydrolyse pro- oxytocin at -Lys-Arg-Ala-Val-.This endopeptidase is present in bovine pituitary neurosecretory granules.
