| oxidoreductases | <enzyme> The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidised is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where o2 is the acceptor. (enzyme nomenclature, 1992, p9) Registry number: EC 1. (12 Dec 1998) |

| oxidoreductases, n-demethylating | <enzyme> Registry number: EC 1.5. (12 Dec 1998) |
| oxidoreductases, o-demethylating | <enzyme> Drug metabolizing enzymes which oxidise methyl ethers. Usually found in liver microsomes. Registry number: EC 1.- (12 Dec 1998) |
| alcohol oxidoreductases | <enzyme> A subclass of enzymes which includes all dehydrogenases acting on primary and secondary alcohols as well as hemiacetals. They are further classified according to the acceptor which can be NAD+ or NADP+ (subclass 1.1.1), cytochrome (1.1.2), oxygen (1.1.3), quinone (1.1.5), or another acceptor (1.1.99). Registry number: EC 1.1 (12 Dec 1998) |

| aldehyde oxidoreductases | <enzyme> Registry number: EC 1.2. (12 Dec 1998) |
| amine oxidoreductases | <enzyme> Enzymes catalyzing the dehydrogenation of secondary amines, introducing a c=n double bond as the primary reaction. In some cases this is later hydrolyzed. Registry number: EC 1.5. (12 Dec 1998) |
| amino acid oxidoreductases | <enzyme> A class of enzymes that catalyze oxidation-reduction reactions of amino acids. Registry number: EC 1.4. (12 Dec 1998) |
| NADH, NADPH oxidoreductases | <enzyme> A group of oxidoreductases that act on NADH or NADPH. In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. This subclass includes only those enzymes in which some other redox carrier is the acceptor. Registry number: EC 1.6. (12 Dec 1998) |
| intramolecular oxidoreductases | <enzyme> Enzymes of the isomerase class that catalyze the oxidation of one part of a molecule with a corresponding reduction of another part of the same molecule. They include enzymes converting aldoses to ketoses (aldose-ketose isomerases), enzymes shifting a carbon-carbon double bond (carbon-carbon double bond isomerases), and enzymes transposing s-s bonds (sulfur-sulfur bond isomerases). Registry number: EC 5.3 (12 Dec 1998) |
| ketone oxidoreductases | <enzyme> Registry number: EC 1.2. (12 Dec 1998) |
