Thus, the substrates of this enzyme are S-adenosyl methionine and glycine, whereas its two products are S-adenosylhomocysteine and sarcosine.
Glycine N-methyltransferase belongs to the family of methyltransferase enzymes. The systematic name of this enzyme class is S-adenosyl-L-methionine:glycine N-methyltransferase. Other names in common use include glycine methyltransferase, S-adenosyl-L-methionine:glycine methyltransferase, and GNMT. This family of enzymes participates in the metabolism of multiple amino acids.
