evolution
methanotrophs produce two genetically unrelated MMOs: soluble MMO (sMMO) expressed by a subset of methanotrophs and membrane-bound, particulate MMO (pMMO) expressed by nearly all methanotrophs. Enzyme sMMO belongs to the larger bacterial multicomponent monooxygenase (BMM) family. In organisms that have genes for both sMMO and pMMO, expression levels are coupled to intracellular copper levels in a mechanism known as the copper switch, wherein sMMO is produced at low copper concentrations while pMMO expression is mildly upregulated and sMMO expression is downregulated when copper is available
metabolism
ammonia-supplied Methylosinus trichosporium OB3b containing soluble methane monooxygenase (sMMO) grow at the fastest rate, while the highest poly-beta-hydroxybutyrate content is obtained by transferring nitrate-supplied bacteria with the expression of particulate methane monooxygenase (pMMO) to nitrogen-free mineral salts (NFMS) + 0.005 mmol/l Cu medium
metabolism
methane hydroxylation through methane monooxygenases is a key aspect due to their control of the carbon cycle in the ecology system
metabolism
methane hydroxylation through methane monooxygenases is a key aspect due to their control of the carbon cycle in the ecology system; the enzyme expresses the soluble enzyme form under copper limitation, and the membrane-bound particulate MMO at high copper-to-biomass ratio, analysis of the mechanism of the copper switch. Transcriptomic profiling of particulate MMO, EC 1.14.18.3, and soluble MMO, using Methylococcus capsulatus DNA microarrays. 137 ORFs are found to be differentially expressed between cells producing sMMO and pMMO, while only minor differences in gene expression are observed between the pMMO-producing cultures. Of these, 87 genes are upregulated during sMMO-producing cells, i.e. during copper-limited growth. Major changes takes place in the respiratory chain between pMMO-and sMMO-producing cells, and quinone are predominantly used as the electron donors for methane oxidation by pMMO. Proposed pathway of methane oxidation in Methylococcus capsulatus cells producing either sMMO or pMMO, overview

metabolism
Methyloceanibacter methanicus {R-67174} is capable of oxidizing methane as sole source of carbon and energy using solely a soluble methane monooxygenase
metabolism
Methyloferula stellata AR4 is an aerobic acidophilic methanotroph, which, in contrast to most known methanotrophs but similar to Methylocella spp., possesses only a soluble methane monooxygenase

analysis of structural and functional differences of sMMO and pMMO, EC 1.14.18.3, substrate/product/cofactor-active site interactions, docking analysis of interactions between cofactors and corresponding enzymes. Molecular simulations and modeling, overview. Structural architecture of sMMO. Enzyme sMMO requires three protein components for maximal catalytic activity: the hydroxylase (MMOH), the reductase (MMOR), and the regulatory protein (MMOB), structure-function relationships, detailed overview. MMOR consists of a NAD binding domain, an FAD-binding domain and a ferredoxin and plays a key role in the delivery of electrons within sMMO enzyme systems. The Fe2S2 domain appears to be the MMOH (methane monooxygenase hydroxylase) binding site, sMMOH docking simulations. MMOB acts as a controller of the methane-to-methanol conversion reaction
