Magnolysin (EC 3.4.24.62, bovine neurosecretory granule protease cleaving pro-oxytocin/neurophysin, pro-oxytocin/neurophysin convertase, prooxyphysin proteinase, pro-oxytocin convertase) is an enzyme.[1][2][3][4][5] 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.
