摘要
A pocketful of coppers: Redox potentiometry and EPR experiments have confirmed that the active site of the particulate methane monooxygenase (pMMO), a membrane-bound enzyme that hydroxylates methane to methanol under ambient conditions, consists of one trinuclear copper cluster (see picture) and one type 2 copper site, in addition to the dinuclear copper cluster revealed previously by X-ray crystallography.
