Tetramethylammonium-corrinoid protein Co-methyltransferase

Tetramethylammonium-corrinoid protein Co-methyltransferase (, mtqB (gene), tetramethylammonium methyltransferase) is an enzyme with systematic name tetramethylammonium:5-hydroxybenzimidazolylcobamide Co-methyltransferase. 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.
