METHANE MONOOXYGENASE HYDROXYLASE
Overview
Methane monooxygenase (MMO), found in aerobic methanotrophic bacteria, catalyzes the O2-dependent conversion of methane to methanol. The soluble, form of the enzyme (sMMO) consists of three components: a reductase, a, regulatory "B" component (MMOB), and a hydroxylase component (MMOH), which, contains a hydroxo-bridged dinuclear iron cluster. Two genera of, methanotrophs, termed Type X and Type II, which differ markedly in, cellular and metabolic characteristics, are known to produce the sMMO. The, structure of MMOH from the Type X methanotroph Methylococcus capsulatus, Bath (MMO Bath) has been reported recently. Two different structures were, found for the essential diiron cluster, depending upon the temperature at, which the diffraction data were collected. In order to extend the, ... [(full description)]
