ID 1.14.13.25 DE methane monooxygenase (soluble). AN methane hydroxylase. CA (1) methane + NADH + O2 + H(+) = methanol + NAD(+) + H2O. CA (2) methane + NADPH + O2 + H(+) = methanol + NADP(+) + H2O. CC -!- The enzyme is soluble, in contrast to the particulate enzyme, CC EC 1.14.18.3. CC -!- Broad specificity; many alkanes can be hydroxylated, and alkenes are CC converted into the corresponding epoxides; CO is oxidized to CO2, CC ammonia is oxidized to hydroxylamine, and some aromatic compounds and CC cyclic alkanes can also be hydroxylated, but more slowly.
