>TIGR02963 xanthine_xdhA xanthine dehydrogenase, small subunit; InterPro: IPR014307 Members of this protein are the small subunit (or, in eukaryotes, the N-terminal domain) of xanthine dehydrogenase, an enzyme of purine catabolism via urate. The small subunit contains both an FAD and a 2Fe-2S cofactor. Aldehyde oxidase (retinal oxidase) appears to have arisen as a neofunctionalisation among xanthine dehydrogenases in eukaryotes. ; GO: 0004854 xanthine dehydrogenase activity, 0004855 xanthine oxidase activity, 0050660 FAD binding.
