ID 2.1.1.20 DE glycine N-methyltransferase. AN glycine methyltransferase. CA glycine + S-adenosyl-L-methionine = H(+) + S-adenosyl-L-homocysteine + CA sarcosine. CC -!- Thought to play an important role in the regulation of methyl group CC metabolism in the liver and pancreas by regulating the ratio between CC S-adenosyl-L-methionine and S-adenosyl-L-homocysteine. CC -!- Inhibited by 5-methyltetrahydrofolate pentaglutamate. CC -!- Sarcosine, which has no physiological role, is converted back into CC glycine by the action of EC 1.5.8.3.
