Kallikrein 13 (, KLK13, kallikrein mK13, mGK-13, mK13, mKLK13, prorenin converting enzyme 1, PRECE-1, prorenin-converting enzyme, PRECE, proteinase P) is an enzyme. This enzyme catalyses hydrolyses mouse Ren2 protein (a species of prorenin present in the submandibular gland) on the carboxy side of the arginine residue at the Lys-Arg- pair in the N-terminus, to yield mature renin.
This enzyme belongs in peptidase family S1A.
