Figure 18.3. Schematic representation of GABA production. Glutamate is taken up by the electrogenic /.-glutamate/ GABA antiporter, the decarboxylation of /.-glutamate via glutamate decarboxylase (GAD) consumes an intracellular H+ and contributes to the generation of proton motive force by GABA. PLP pyridoxal-5 -phosphate.

Aldol addition of glycine to aldehydes catalyzed by threonine aldolases. PLP, Pyridoxal-5 -phosphate. 

Catalytic cycle for the m-TA-catalyzed amination. PLP, pyridoxal-5 -phosphate PMP, pyridoxamine-5 -phosphate. 

Set of accessible threonine aldolases for adol addition of glycine to aldehydes. Abbreviations PLP=Pyridoxal-5 -phosphate.
