Glycine/sarcosine N-methyltransferase (EC 2.1.1.156, ApGSMT, glycine-sarcosine methyltransferase, GSMT, GMT, glycine sarcosine N-methyltransferase, S-adenosyl-L-methionine:sarcosine N-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:glycine(or sarcosine) N-methyltransferase (sarcosine(or N,N-dimethylglycine)-forming).[1][2][3] This enzyme catalyses the following chemical reaction
- 2 S-adenosyl-L-methionine + glycine 2 S-adenosyl-L-homocysteine + N,N-dimethylglycine (overall reaction)
- (1a) S-adenosyl-L-methionine + glycine S-adenosyl-L-homocysteine + sarcosine
- (1b) S-adenosyl-L-methionine + sarcosine S-adenosyl-L-homocysteine + N,N-dimethylglycine
This enzyme participates in biosynthesis of betaine from glycine in cyanobacterium Aphanocthece halophytica.
