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

Inactive 2-(methylthio)ethanesulfonic acid (CH3-S-CoM) reductase was partially activated by exposure to light. This simplified system replaces the complex enzymatic system of protein components A2, A3a, A3b, and ATP, which previously represented the only available means of reactivating the enzyme. Components

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
