==FAD and NADH binding domain of methane monooxygenase reductase from Methylococcus capsulatus (Bath)==
-
Soluble methane monooxygenase (sMMO) catalyzes the hydroxylation of, methane by dioxygen to methanol, the first step in carbon assimilation by, methanotrophs. This multicomponent system transfers electrons from NADH, through a reductase component to the non-heme diiron center in the, hydroxylase where O(2) is activated. The reductase component comprises, three distinct domains, a [2Fe-2S] ferredoxin domain along with FAD- and, NADH-binding domains. We report the solution structure of the reduced 27.6, kDa FAD- and NADH-binding domains (MMOR-FAD) of the reductase from, Methylococcus capsulatus (Bath). The FAD-binding domain consists of a, six-stranded antiparallel beta-barrel and one alpha-helix, with the first, 10 N-terminal residues unstructured. In the interface between the two, domains, the FAD cofactor is tightly bound in an unprecedented extended, conformation. The NADH-binding domain consists of a five-stranded parallel, beta-sheet with four alpha-helices packing closely around this sheet., MMOR-FAD is structurally homologous to other FAD-containing, oxidoreductases, and we expect similar structures for the FAD/NADH-binding, domains of reductases that occur in other multicomponent monooxygenases.

== Function ==

[https://www.uniprot.org/uniprot/MMOC_METCA MMOC_METCA] Responsible for the initial oxygenation of methane to methanol in methanotrophs. It also catalyzes the monohydroxylation of a variety of unactivated alkenes, alicyclic, aromatic and heterocyclic compounds. The component C is the iron-sulfur flavoprotein of sMMO.
