| formate dehydrogenases | <enzyme> Flavoproteins that catalyze reversibly the reduction of carbon dioxide to formate. Many compounds can act as acceptors, but the only physiologically active acceptor is NAD. The enzymes are active in the fermentation of sugars and other compounds to carbon dioxide and are the key enzymes in obtaining energy when bacteria are grown on formate as the main carbon source. They have been purified from bovine blood. Chemical name: Formate:NAD+ oxidoreductase Registry number: EC 1.2.1.2 (12 Dec 1998) |
| formate hydrogen lyase | <enzyme> Consists of EC 1.2.1.2, formate dehydrogenase, plus EC 1.12.1.2, hydrogen dehydrogenase Registry number: EC 1.- Synonym: formate dehydrogenase h, fdhh gene product, fdhf gene product, hyc gene product (26 Jun 1999) |
| formate-NADP oxidoreductase | <enzyme> Separate from formate dehydrogenase Registry number: EC 1.6.- (26 Jun 1999) |
| formate-tetrahydrofolate ligase | <enzyme> An enzyme that catalyses the formation of 10-formyltetrahydrofolate from formate and tetrahydrofolate in the presence of ATP. This enzyme has been found in pigeon liver, human erythrocytes and some microorganisms. Chemical name: Formate:tetrahydrofolate ligase (ADP-forming) Registry number: EC 6.3.4.3 (12 Dec 1998) |
