prolyl

prolyl
- p. dipeptidase an enzyme cleaving l-p.-amino acid bonds in dipeptides containing N-terminal p. residues. SYN: iminodipeptidase, prolinase, prolylglycine dipeptidase.
- p. hydroxylase an enzyme that catalyzes the hydroxylation of certain p. residues in collagen precursors using molecular oxygen, ferrous ion, ascorbic acid, and α-ketoglutarate; a vitamin C deficiency directly affects the activity of this enzyme; one form of this enzyme (p. 4-hydroxylase) synthesizes 4-hydroxyprolyl residues while another produces 3-hydroxyprolyl residues.
