In enzymology, a glycine N-methyltransferase (EC 2.1.1.20) is an enzyme that catalyzes the chemical reaction 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.

This family of enzymes participates in the metabolism of multiple amino acids.
