General annotation (Comments)

Function	Electron transfer component of 2-halobenzoate 1,2-dioxygenase system.
Catalytic activity	Reduced ferredoxin + NAD+ = oxidized ferredoxin + NADH.
Cofactor	Binds 1 FAD per subunit By similarity. Binds 1 2Fe-2S cluster per subunit By similarity.
Pathway	Xenobiotic degradation; benzoate degradation via CoA ligation.
Subunit structure	Monomer. It is part of 2-halobenzoate dioxygenase two component enzyme system. The other component is a dioxygenase component consisting of 3 large (CbdA) subunits and 3 small (CbdB) subunits.
Sequence similarities	Belongs to the bacterial ring-hydroxylating dioxygenase ferredoxin reductase family. Contains 1 2Fe-2S ferredoxin-type domain. Contains 1 FAD-binding FR-type domain.
