FAD_binding_5

 FAD_binding_5
PFAM accession number:PF00941
Interpro abstract (IPR002346):

Oxidoreductases, that also bind molybdopterin, have essentially no similarity outside this common domain. They include aldehyde oxidase ( EC 1.2.3.1 ), that converts an aldehyde and water to an acid and hydrogen peroxide, and xanthine dehydrogenase ( EC 1.1.1.204 ), that converts xanthine to urate. These enzymes require molybdopterin and FAD as cofactors and have and two 2FE-2S clusters. Another enzyme that contains this domain is the Pseudomonas thermocarboxydovorans carbon monoxide oxygenase.

GO process:oxidation-reduction process (GO:0055114)
GO function:oxidoreductase activity (GO:0016491)
