| Type: | Family | Name: | Ammonia monooxygenase/particulate methane monooxygenase, subunit C |
| Description: | Ammonia monooxygenase and the particulate methane monooxygenase are both integral membrane proteins, occurring in ammonia oxidisers and methanotrophs respectively, which are thought to be evolutionarily related []. These enzymes have a relatively wide substrate specificity and can catalyse the oxidation of a range of substrates including ammonia, methane, halogenated hydrocarbons and aromatic molecules []. These enzymes are composed of 3 subunits - A (), B () and C () - and contain various metal centres, including copper. Particulate methane monooxygenase from Methylococcus capsulatus str. Bathis an ABC homotrimer, which contains mononuclear and dinuclear copper metal centres, and a third metal centre containing a metal ion whose identity in vivo is not certain[].The C subunit from Methylococcus capsulatus str. Bathresides primarily in the membrane and consists of five transmembrane helices. Several conserved residues contribute to a metal binding centre []. | Short Name: | NH3_CH4_mOase_C |
