MetaCyc Reaction: 2.1.1.258

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Protein-Modification Reactions
Reactions Classified By Substrate Macromolecule Reactions Protein-Reactions Protein-Modification Reactions

EC Number: 2.1.1.258

Enzymes and Genes:

Moorella thermoacetica : methyltetrahydrofolate:corrinoid/iron-sulfur protein methyltransferase Inferred from experiment : acsE

In Pathway: reductive acetyl coenzyme A pathway

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: 5-methyltetrahydrofolate:corrinoid/iron-sulfur protein Co-methyltransferase

Enzyme Commission Synonyms: acsE (gene name)

Standard Gibbs Free Energy (ΔrG in kcal/mol): 16.661118 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Catalyses the transfer of a methyl group from the N5 group of methyltetrahydrofolate to the 5-methoxybenzimidazolylcobamide cofactor of a corrinoid/Fe-S protein. Involved, together with EC 1.2.7.4, carbon-monoxide dehydrogenase (ferredoxin) and EC 2.3.1.169, CO-methylating acetyl-CoA synthase, in the reductive acetyl coenzyme A (Wood-Ljungdahl) pathway of autotrophic carbon fixation in various bacteria and archaea.
