Trimethylamine-corrinoid protein Co-methyltransferase

Trimethylamine-corrinoid protein Co-methyltransferase (, mttB (gene), trimethylamine methyltransferase) is an enzyme with systematic name trimethylamine:5-hydroxybenzimidazolylcobamide Co-methyltransferase. This enzyme catalyses the following chemical reaction


 * trimethylamine + [Co(I) trimethylamine-specific corrinoid protein] $$\rightleftharpoons$$ [methyl-Co(III) trimethylamine-specific corrinoid protein] + dimethylamine

This enzyme is involved in methanogenesis from trimethylamine.
