Toluene-4-monooxygenase effector protein complex (T4mo), Rieske ferredoxin subunit; The Rieske domain is a [2Fe-2S] cluster binding domain involved in electron transfer. T4mo is a four-protein complex that catalyzes the NADH- and O2-dependent hydroxylation of toluene to form p-cresol. T4mo consists of an NADH oxidoreductase (T4moF), a diiron hydroxylase (T4moH), a catalytic effector protein (T4moD), and a Rieske ferredoxin (T4moC). T4moC contains a Rieske domain and functions as an obligate electron carrier between T4moF and T4moH. Rieske ferredoxins are found as subunits of membrane oxidase complexes, cis-dihydrodiol-forming aromatic dioxygenases, bacterial assimilatory nitrite reductases, and arsenite oxidase. Rieske ferredoxins are also found as soluble electron carriers in bacterial dioxygenase and monooxygenase complexes.
