Dimethylglycine N-methyltransferase

Dimethylglycine N-methyltransferase (, BsmB, DMT) is an enzyme with systematic name S-adenosyl-L-methionine:N,N-dimethylglycine N-methyltransferase (betaine-forming). This enzyme catalyses the following chemical reaction


 * S-adenosyl-L-methionine + N,N-dimethylglycine $$\rightleftharpoons$$ S-adenosyl-L-homocysteine + betaine

This enzyme is purified from the marine cyanobacterium ''Synechococcus sp. WH8102''.
