Activating Compound

Activating Compound Comment Organism Structure
RamA a 60-kDa monomeric iron sulfur protein, is a protein required for reductive activation of corrinoid-dependent methylamine methyltransferase reactions in methanogenic archaea, it is required for in vitro ATP-dependent reductive activation of trimethylamine:CoM methyl transfer mediating the ATP-dependent reductive activation of Co(II) corrinoid to the Co(I) state for the trimethylamine corrinoid protein, MttC, overview Methanosarcina barkeri

General Information

General Information Comment Organism
metabolism archaeal methane formation from methylamines is initiated by distinct methyltransferases with specificity for monomethylamine, dimethylamine, or trimethylamine. Each methylamine methyltransferase methylates a cognate corrinoid protein, which is subsequently demethylated by a second methyltransferase to form methyl-coenzyme M, the direct methane precursor Methanosarcina barkeri
