General annotation (Comments)

Function

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.

Catalytic activity

Methane + NAD(P)H + O2 = methanol + NAD(P)+ + H2O.

Cofactor

Binds 1 2Fe-2S cluster.

Subunit structure

The soluble methane monooxygenase (sMMO) consists of four components A/MMOH (composed of alpha/mmoX, beta/mmoY and gamma/mmoZ), B/MMOB (mmoB), C/MMOR (mmoC) and D/MMOD (mmoD).

Sequence similarities

Contains 1 2Fe-2S ferredoxin-type domain.

Contains 1 FAD-binding FR-type domain.
