'''Methane monooxygenase''' (MMO) catalyzes the oxidation of the C-H bond of methane and other alkanes. MMO catalyzes the conversion of CH<sub>4</sub> and O2 to CH3OH and H2O using NADPH as reducing agent. The '''soluble MMO (sMMO)''' has Fe-O-Fe in its active site while the '''particulate MMO (pMMO)''' has Cu in it. MMO is composed of 3 subunits.<br />
