Protein

Methane monooxygenase component C

Gene

mmoC

Organism
Methylococcus capsulatus (strain ATCC 33009 / NCIMB 11132 / Bath)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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 activityi

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

Cofactori

Binds 1 2Fe-2S cluster.
