Protein

4-aminobutyrate aminotransferase

Gene

UGA1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Required for the degradation of gamma-aminobutyric acid (GABA), which is important for utilization of GABA as nitrogen source and for oxidative stress tolerance. Deaminates GABA to succinate semialdehyde, which in turn is converted to succinate by the succinate-semialdehyde dehydrogenase UGA2. Cannot transaminate beta-alanine (BAL).3 Publications

Catalytic activityi

4-aminobutanoate + 2-oxoglutarate = succinate semialdehyde + L-glutamate.

pH dependencei

Optimum pH is 8.3.1 Publication
