Glicin/sarkozin N-metiltransferaza (EC 2.1.1.156, ApGSMT, glicin-sarkozinska metiltransferaza, GSMT, GMT, glicin sarkozinska N-metiltransferaza, S-adenozil-L-metionin:sarkozin N-metiltransferaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:glicin(or sarkozin) N-metiltransferaza (sarkozin(or formira N,N-dimetilglicin)).[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 2 S-adenozil-L-metionin + glicin 2 S-adenozil-L-homocistein + N,N-dimetilglicin (sveukupna reakcija)
- (1a) S-adenozil-L-metionin + glicin S-adenozil-L-homocistein + sarkozin
- (1b) S-adenozil-L-metionin + sarkozin S-adenozil-L-homocistein + N,N-dimetilglicin
Cijanobakterija Aphanocthece halophytica sintetiše betain iz glicina putem metilacije koja se odvija u tri koraka. Ovaj enzim posreduje prvi korak te sekvence.
