proline


proline
Pyrrolidine-2-carboxylic acid; the l-isomer is found in proteins, especially the collagens. SYN: pyrrolidine-2-carboxylate.
- p. aminopeptidase SYN: p. iminopeptidase.
- p. dehydrogenase SYN: pyrroline-2-carboxylate reductase, pyrroline-5-carboxylate reductase.
- p. dipeptidase an enzyme cleaving aminoacyl-l-p. bonds in dipeptides containing a C-terminal p. residue; a deficiency of this enzyme results in hyperimidodipeptiduria. SYN: imidodipeptidase, peptidase D, prolidase.
- p. iminopeptidase a hydrolase cleaving l-prolyl residues from the N-terminal position in peptides. SYN: p. aminopeptidase.
- p. oxidase SYN: pyrroline-2-carboxylate reductase, pyrroline-5-carboxylate reductase.
- p. racemase an enzyme that reversibly converts d-p. to l-p..
- d-p. reductase an oxidoreductase reversibly reacting d-p. with NADH to produce 5-aminovalerate and NAD+.
