FAD_binding_1

 FAD_binding_1
PFAM accession number:PF00667
Interpro abstract (IPR003097):

This FAD-binding domain can be found in sulfite reductase [NADPH] flavoprotein alpha-component CysJ, NADPH cytochrome P450 reductase, nitric oxide synthase and methionine synthase reductase. CysJ is a component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide [ (PUBMED:10860732) ]. The structure of the nitric oxide synthase FAD-binding domain has been solved [ (PUBMED:11473123) ].

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

This is a PFAM domain. For full annotation and more information, please see the PFAM entry FAD_binding_1
