Glicin oksidaza (EC 1.4.3.19, glicinska oksidaza) je enzim sa sistematskim imenom glicin:kiseonik oksidoreduktaza (deaminacija).[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju:
- glicin + H2O + O2 glioksilat + NH3 +H2O2 (sveukupna reakcija)
- (1a) glicin + O2 2-iminoacetat +H2O2
- (1b) 2-iminoacetat +H2O glioksilat + NH3
Ovaj enzim je flavoenzim koji sadrži nekovalentno vezani FAD. Enzim iz Bacillus subtilis je aktivan sa glicinom, sarkozinom, N-etilglicin, D-alanin, D-alfa-aminobutirat, D-prolin, D-pipekolat i Nmetil-D-alanin.
