GABA(γ-aminobutyric acid) is a non-protein amino acid that can be accumulated via permease-mediated uptake by Uga4p, Put4p, and Gap1p. GABA can also be produced via glutamate degradation by the glutamate decarboxylase, this variant of the pathway includes a 2-oxoglutarate-dependent 4-aminobutyrate transaminase and an NAD+-dependent dehydrogenase. This combination of enzymes has been documented in bacteria and animals and in some plants. Regarding the hydrogenase, NAD-specific variants have been studied from many bacteria, plant and animals.
