| racemase | <enzyme> Enzymes that catalyze inversion of the configuration around an asymmetric carbon in a substrate having one (racemase) or more (epimerase) centre(s) of asymmetry. For example; hydroxyproline, ribulose phosphate). Registry number: EC 5.1 (21 Jun 2000) |
| glutamate racemase | <enzyme> Catalyses the conversion of l-glutamate to d-glutamate; muri protein was isolated from e. Coli Registry number: EC 5.1.1.3 Synonym: muri protein, muri gene product (26 Jun 1999) |
| hydantoin racemase | <enzyme> Catalyses the racemization of 5-substituted hydantoins in pseudomonas to their corresponding n-carbamoyl amino acids and ultimately to the corresponding l-amino acid Registry number: EC 5.1.99.- Synonym: hyue protein, hyue gene product (26 Jun 1999) |
| lysine racemase | <enzyme> Interconverts the d- and l-isomers Registry number: EC 5.1.1.5 (26 Jun 1999) |
| procollagen-proline dioxygenase | <enzyme> A mixed-function oxygenase that catalyses the hydroxylation of a prolyl-glycyl-containing-peptide, usually in protocollagen, to a hydroxyprolylglycyl-containing-peptide. The enzyme utilises molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. Chemical name: Procollagen-L-proline,2-oxoglutarate:oxygen oxidoreductase Registry number: EC 1.14.11.2 (12 Dec 1998) |
| proline | <amino acid> One of the 20 amino acids directly coded for in proteins. Structure differs from all the others, in that its side chain is bonded to the nitrogen of the _ amino group, as well as the _ carbon. This makes the amino group a secondary amine and so proline is described as an imino acid. Has strong influence on secondary structure of proteins and is much more abundant in collagens than in other proteins, occurring especially in the sequence glycine proline hydroxyproline. A proline rich region seems to characterise the binding site of SH3 domains. (18 Nov 1997) |
| proline, 2-oxoglutarate 3-dioxygenase | <enzyme> Prolyl 3-hydroxylase is separate enzyme from prolyl 4-hydroxylase; catalyses post translational modification of collagen Registry number: EC 1.14.11.7 Synonym: proline 3-hydroxylase, prolyl 3-hydroxylase (26 Jun 1999) |
| proline aminopeptidase | A hydrolase cleaving l-proline residues from the N-terminal position in peptides. Synonym: proline aminopeptidase. (05 Mar 2000) |
| proline-beta-naphthylamidase | <enzyme> From pig intestinal mucosa; hydrolyzes proline-beta-naphthylamidase; distinct from proline aminopeptidase; inhibited by active site serine-specific protease inhibitors Registry number: EC 3.4.11.- Synonym: pro-naphthylamidase (26 Jun 1999) |
| proline dehydrogenase | An oxidoreductase reducing 1-pyrroline-2-carboxylate to l-proline with NAD(P)H. Synonym: proline dehydrogenase, proline oxidase. (05 Mar 2000) |
| proline dipeptidase | <enzyme> An enzyme cleaving aminoacyl-l-proline bonds in dipeptides containing a C-terminal prolyl residue; a deficiency of this enzyme results in hyperimidodipeptiduria. Synonym: imidodipeptidase, peptidase D, prolidase. (05 Mar 2000) |
| proline iminopeptidase | A hydrolase cleaving l-proline residues from the N-terminal position in peptides. Synonym: proline aminopeptidase. (05 Mar 2000) |
