Soluble methane monooxygenase: activation of dioxygen and methane

The mechanisms by which soluble methane monooxygenase uses dioxygen to convert methane selectively to methanol have come into sharp focus. Diverse techniques have clarified subtle details about each step in the reaction, from binding and activating dioxygen, to hydroxylation of alkanes and other substrates, to the electron transfer events required to complete the catalytic cycle.
