CC -!- FUNCTION: Reductase component of the toluene-4-monooxygenase
CC multicomponent enzyme system which catalyzes the O2- and NADH-dependent
CC hydroxylation of toluene to form p-cresol (PubMed:15240250,
CC PubMed:17964805). Ferredoxin reductase catalyzes the transfer of
CC electrons from NADH to ferredoxin (TmoC) (PubMed:17964805).
CC {ECO:0000269|PubMed:15240250, ECO:0000269|PubMed:17964805,
CC ECO:0000305|PubMed:1429451}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + NAD(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NADH + 2
CC oxidized [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:16521, Rhea:RHEA-

CC Evidence={ECO:0000269|PubMed:17964805};
CC -!- COFACTOR:

CC Evidence={ECO:0000269|PubMed:17964805, ECO:0000269|PubMed:26309236};
CC Note=Binds 1 FAD per subunit. {ECO:0000269|PubMed:17964805};
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000269|PubMed:17964805, ECO:0000269|PubMed:26309236};
CC Note=Binds 1 2Fe-2S cluster. {ECO:0000269|PubMed:17964805,
CC ECO:0000269|PubMed:26309236};
CC -!- PATHWAY: Xenobiotic degradation; toluene degradation.
CC {ECO:0000305|PubMed:15240250}.
CC -!- SUBUNIT: Monomer (PubMed:26309236). The alkene monooxygenase
CC multicomponent enzyme system is composed of an electron transfer
CC component and a monooxygenase component interacting with the effector
CC protein TmoD. The electron transfer component is composed of a
CC ferredoxin reductase (TmoF) and a ferredoxin (TmoC), and the
CC monooxygenase component is formed by a heterohexamer (dimer of
CC heterotrimers) of two alpha subunits (TmoA), two beta subunits (TmoE)
CC and two gamma subunits (TmoB). {ECO:0000269|PubMed:26309236}.
CC -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase
CC ferredoxin reductase family. {ECO:0000305}.
