Protein

Methane monooxygenase component A gamma chain

Gene

mmoZ

Organism
Methylococcus capsulatus (strain ATCC 33009 / NCIMB 11132 / Bath)
Status
Reviewed - Annotation score: 3 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.

Catalytic activityi

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

Interactioni

Subunit structurei

M.capsulatus has two forms of methane monooxygenase, a soluble and a membrane-bound type. The soluble type consists of four components (A to D): protein A, comprising three chains, in an alpha-2, beta-2, gamma-2 configuration, is a nonheme iron protein containing an unusual mu-hydroxo bridge structure at its active site and interacts with both oxygen and methane.
