| duroquinol oxidase | <enzyme> Consists of fixn, fixo, and fixp proteins in bradyrhizobium, in which fixo and fixp are c-type cytochromes; does not contain cytochromes, probably a flavoprotein; a proto-haem containing oxidase expressed by the cyoabc locus in paracoccus denitrificans Registry number: EC 1.- Synonym: aroid alternative oxidase, quinol oxidase, trypanosoma alternative oxidase, cyanide-resistant alternative oxidase, cytochrome bb3, cytochrome bb(3) (26 Jun 1999) |

| indole-3-ethanol oxidase | <enzyme> Involved in conversion of indole-3-ethanol to indole-3-acetic acid; isolated from seeds of the bean phaseolus vulgaris; not stimulated by nadp or fad; do not confuse with nad- or nadp-dependent indole-3-ethanol oxidases Registry number: EC 1.1.- Synonym: tryptophol oxidase (26 Jun 1999) |
| indophenol oxidase | <enzyme> Also oxidises tetrazolium salts in the presence of phenazine methosulfate; this is not EC 1.9.3.1 Registry number: EC 1.- (26 Jun 1999) |
| octopine oxidase | <enzyme> Catalyses oxidative cleavage of octopine into l-arginine and pyruvate; no required cofactors; activity requires ooxa and ooxb gene products; isolated from agrobacterium tumefaciens Registry number: EC 1.5.99.- (26 Jun 1999) |
| oxidase | Classically, one of a group of enzymes, now termed oxidoreductases (EC class 1), that bring about oxidation by the addition of oxygen to a metabolite or by the removal of hydrogen or of one or more electrons. Oxidase is now used for those cases in which O2 acts as an acceptor (of H or of electrons); those removing hydrogen are now termed dehydrogenases. For individual oxidases, see the specific names. Direct oxidase, originally, an oxidase catalyzing the transfer of O2 directly to other bodies; now termed oxygenase. Indirect oxidase, originally, an oxidase that acts by reducing a peroxide; now termed peroxidase. Terminal oxidase, the last protein in the electron transport, respiratory chain. In mammals this is cytochrome c oxidase. (05 Mar 2000) |
| oxidase reaction | The formation of indol blue when a blood smear containing myeloid leukocytes is treated with a mixture of alpha-naphthol and p-dimethylaniline sulfate; the myeloid leukocytes contain an oxidase that catalyses this reaction, the lymphoid leukocytes do not, in bacteriology, a reaction that depends on the presence of certain oxidases in some bacteria that catalyze the transport of electrons between electron donors in the bacteria and an oxidation reduction dye, such as tetramethyl-p-phenylenediamine; the dye is reduced to a blue or black colour.
