ID   2.1.1.162
DE   glycine/sarcosine/dimethylglycine N-methyltransferase.
AN   glycine sarcosine dimethylglycine N-methyltransferase.
AN   GSDMT.
CA   glycine + 3 S-adenosyl-L-methionine = glycine betaine + 3 H(+) +
CA   3 S-adenosyl-L-homocysteine.
CC   -!- Unlike EC 2.1.1.156, EC 2.1.1.157 and EC 2.1.1.161, this enzyme, from
CC       the halophilic methanoarchaeon Methanohalophilus portucalensis,
CC       can methylate glycine and all of its intermediates to form the
CC       compatible solute betaine.
