InterPro domain: IPR002346

Oxidoreductases, that also bind molybdopterin, have essentially no similarity outside this common domain. They include aldehyde oxidase ( 1.2.3.1 ), that converts an aldehyde and water to an acid and hydrogen peroxide, and xanthine dehydrogenase ( 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.
