General Information | Comment | Organism |
---|---|---|
metabolism | biochemistry of methane formation by Methanosarcina species from monomethylamine, dimethylamine, and trimethylamine: methanogenesis from these substrates is initiated by three methyltransferases that specifically methylate their cognate corrinoid proteins with one of these methylamines, cf. EC 2.1.1.250 and EC 2.1.1.248, overview | Methanosarcina barkeri |
physiological function | the enzyme is involved in the corrinoid-dependent demethylation of methylamines, which are used for coenzyme M methylation | Methanosarcina barkeri |
