Application
Ammonium 2-(methylthio)ethanesulfonate (Methyl coenzyme M) is converted into methane by the enzyme Methyl-coenzyme M reductase (MCR) derived from methanogenic archaea. Methy-coenzyme M is used in studies on methanogenic (methane-producing) enzymatic processes.

Buffer-soluble extracts of acetate-grown Methanosarcina barkeri catalyzed methanogenesis from acetate in the presence of hydrogen and ATP. The rates of methane formation from either acetate plus ATP, or acetylphosphate without ATP added, were approximately doubled by the addition of coenzyme

Methyl-coenzyme M reductase (MCR) catalyses the methane-forming step in the energy metabolism of methanogenic Archaea. It brings about the reduction of methyl-coenzyme M (CH3-S-CoM) by 7-mercaptoheptanoylthreonine phosphate (H-S-HTP). Methanobacterium thermoautotrophicum contains two isoenzymes of MCR, designated MCR I and MCR

Cell-free extracts of Methanobacterium thermoautotrophicum (strain delta H) were found to contain high concentrations of inorganic pyrophosphate (up to 40 mM). The compound was accumulated by the organism despite high activity of inorganic pyrophosphatase which was found to be present

Lake Pavin is a meromictic crater lake located in the French Massif Central area. In this ecosystem, most methane (CH(4)) produced in high quantity in the anoxic bottom layers, and especially in sediments, is consumed in the water column, with

Methyl-coenzyme M reductase (MCR), the enzyme responsible for the microbial formation of methane, is a 300-kilodalton protein organized as a hexamer in an alpha2beta2gamma2 arrangement. The crystal structure of the enzyme from Methanobacterium thermoautotrophicum, determined at 1.45 angstrom resolution for
