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.

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

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

When titanium(III) citrate was used as electron donor for the reduction of methyl coenzyme M by the methyl coenzyme M methylreductase system of Methanobacterium thermoautotrophicum delta H, component A1 was no longer required. The simpler system thus obtained required components

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) 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
