| peptidyl-Asp metalloendopeptidase | <enzyme> Extracellular metalloproteinase secreted by a pseudomonas fragi mutant; partial amino acid sequence given in first source Registry number: EC 3.4.24.33 Synonym: endopeptidase asp-n (26 Jun 1999) |
|---|---|
| peptidyl-dipeptidase A | <enzyme> A hydrolase cleaving C-terminal dipeptides from a variety of substrates, including angiotensin I, which is converted to angiotensin II and histidylleucine. An important step in the metabolism of certain vasopressor agents. It is a chloride-dependent, zinc glycoprotein that is generally membrane-bound and active at neutral pH. Only single dipeptides are released from angiotensin I and bradykinin because of the lack of activity on bonds involving proline. It may also have endopeptidase activity on some substrates. Registry number: EC 3.4.15.1 Synonym: carboxycathepsin, dipeptidyl carboxypeptidase, kinase II, peptidase P. (22 Sep 2002) |
| peptidyl leukotrienes | Leukotrienes having amino acids present (even single amino acids) although not true peptides; e.g., LTC4 is an S-substituted glutathione, LTD4 is an S-substituted cysteinylglycine, LTE4 is an S-substituted cysteine, and LTF4 (also known as gamma-glutamyl-LTE4) is an S-substituted gamma-glutamylcysteine.

| peptidyl-Lys metalloendopeptidase | <enzyme> From lysobacter enzymogenes; cleaves at the carboxyl side of lysine residues; active at pH 9;endoproteinase lys-c (EC 3.4.99.30) was combined with EC 3.4.24.20 in 1992 enzyme nomenclature Registry number: EC 3.4.24.20 Synonym: endoprotease lys-c, endopeptidase lys-c, endoproteinase lys-c, lysc protease (26 Jun 1999) |
| peptidyl prolyl cis trans isomerase | See: PPIase and immunophilin. (18 Nov 1997) |
| aldehyde-ketone transferases | <enzyme> Enzymes that catalyze the transfer of aldehyde or ketone residues. Registry number: EC 2.2 (12 Dec 1998) |
| alkyl and aryl transferases | <enzyme> A somewhat heterogeneous class of enzymes that catalyze the transfer of alkyl or related groups (excluding methyl groups). Registry number: EC 2.5 (12 Dec 1998) |
| carboxyl and carbamoyl transferases | <enzyme> A group of enzymes that catalyze the transfer of carboxyl- or carbamoyl- groups. Registry number: EC 2.1.3 (12 Dec 1998) |
| CoA transferases | Thiaphorases;enzymes transferring CoA from acetyl-CoA or succinyl-CoA to other acyl radicals. (05 Mar 2000) |
| coenzyme a-transferases | <enzyme> Enzymes which transfer coenzyme a moieties from acyl- or acetyl-CoA to various carboxylic acceptors forming a thiol ester. Enzymes in this group are instrumental in ketone body metabolism and utilization of acetoacetate in mitochondria. Registry number: EC 2.8.3 (12 Dec 1998) |
| hydroxymethyl and formyl transferases | <enzyme> Enzymes that catalyze the transfer of hydroxymethyl or formyl groups. Registry number: EC 2.1.2 (12 Dec 1998) |
| nitrogenous group transferases | <enzyme> Enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. Registry number: EC 2.6 (12 Dec 1998) |
| sulfur group transferases | <enzyme> Enzymes that catalyze the transfer of sulfur atoms (2.8.1), sulfur groups (2.8.2) or coenzyme a (2.8.3). Registry number: EC 2.8 (12 Dec 1998) |
| intramolecular transferases | <enzyme> Enzymes of the isomerase class that catalyze the transfer of acyl-, phospho-, amino- or other groups from one position within a molecule to another. Registry number: EC 5.4 (12 Dec 1998) |
| one-carbon group transferases | <enzyme> A subclass of transferases that transfer chemical groups containing a single carbon. These include the methyltransferases, the hydroxymethyl and formyl transferases, the carboxyl and carbamoyl transferases, and the amidinotransferases. Registry number: EC 2.1 (12 Dec 1998) |
