Chains	Accession	Name	Description	Comments	Source
A, B	PF00667	FAD binding domain (FAD_binding_1)	FAD binding domain	This domain is found in sulfite reductase, NADPH cytochrome P450 reductase, Nitric oxide synthase and methionine synthase reductase. This domain consists of a RIFT-like beta-barrel containing an inserted alpha-helical subdomain.	Domain
A, B	PF00175	Oxidoreductase NAD-binding domain (NAD_binding_1)	Oxidoreductase NAD-binding domain	Xanthine dehydrogenases, that also bind FAD/NAD, have essentially no similarity.	Domain
A, B	PF00258	Flavodoxin (Flavodoxin_1)	Flavodoxin		Domain
