Aldehyde Oxidoreductases

Medical Definition:
CAS Number:	EC 1.2.
Previously Indexed:	Oxidoreductases (1966-1972)

Aldehyde Oxidoreductases Categories.

	Aldehyde Dehydrogenase - An enzyme that oxidizes an aldehyde in the presence of NAD+ and water to an acid and NADH. EC 1.2.1.3. Before 1978, it was classified as EC 1.1.1.70.
	Aldehyde Oxidase - An aldehyde oxidoreductase expressed predominantly in the LIVER; LUNGS; and KIDNEY. It catalyzes the oxidation of a variety of organic aldehydes and N-heterocyclic compounds to CARBOXYLIC ACIDS, and also oxidizes QUINOLINE and PYRIDINE derivatives. The enzyme utilizes molybdenum cofactor and FAD as cofactors.
	Aspartate-Semialdehyde Dehydrogenase - An enzyme that catalyzes the conversion of L-aspartate 4-semialdehyde, orthophosphate, and NADP+ to yield L-4-aspartyl phosphate and NADPH. EC 1.2.1.11.
	Formate Dehydrogenases - 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. EC 1.2.1.2.
	Glyceraldehyde-3-Phosphate Dehydrogenases - Enzymes that catalyze the dehydrogenation of GLYCERALDEHYDE 3-PHOSPHATE. Several types of glyceraldehyde-3-phosphate-dehydrogenase exist including phosphorylating and non-phosphorylating varieties and ones that transfer hydrogen to NADP and ones that transfer hydrogen to NAD.
