Reductase component of the toluene-4-monooxygenase multicomponent enzyme system which catalyzes the O2- and NADH-dependent hydroxylation of toluene to form p-cresol (PubMed:15240250, PubMed:17964805). Ferredoxin reductase catalyzes the transfer of electrons from NADH to ferredoxin (TmoC) (PubMed:17964805). H(+) + NAD(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NADH + 2 oxidized [2Fe-2S]-[ferredoxin] Binds 1 FAD per subunit. Binds 1 2Fe-2S cluster. Xenobiotic degradation; toluene degradation. Monomer (PubMed:26309236). The alkene monooxygenase multicomponent enzyme system is composed of an electron transfer component and a monooxygenase component interacting with the effector protein TmoD. The electron transfer component is composed of a ferredoxin reductase (TmoF) and a ferredoxin (TmoC), and the monooxygenase component is formed by a heterohexamer (dimer of heterotrimers) of two alpha subunits (TmoA), two beta subunits (TmoE) and two gamma subunits (TmoB). Belongs to the bacterial ring-hydroxylating dioxygenase ferredoxin reductase family.
