Tetramethylammonium-corrinoid protein Co-methyltransferase explained

Tetramethylammonium-corrinoid protein Co-methyltransferase
Ec Number:2.1.1.252

Tetramethylammonium-corrinoid protein Co-methyltransferase (mtqB (gene), tetramethylammonium methyltransferase) is an enzyme with systematic name tetramethylammonium:5-hydroxybenzimidazolylcobamide Co-methyltransferase.[1] This enzyme catalyses the following chemical reaction

tetramethylammonium + [Co(I) tetramethylammonium-specific corrinoid protein]

\rightleftharpoons

[methyl-Co(III) tetramethylammonium-specific corrinoid protein] + trimethylamine

This enzyme is involved in methanogenesis from tetramethylammonium.
