Methane monooxygenase or MMO is an enzyme capable of oxidizing the C-H bond in methane as well as other alkanes. Methane monooxygenase belongs to the class of oxidoreductase enzymes (EC 1.14.13.25). There are two well-studied forms of MMO: the soluble form (sMMO) and the particulate form (pMMO). The active site in sMMO contains a di-iron center bridged by an oxygen atom (Fe-O-Fe) whereas the active site in pMMO utilizes copper although some propose that pMMO also uses iron.
