4-aminobutyrate aminotransferase

Gene

GATA

Organism
Ustilago maydis (strain 521 / FGSC 9021) (Corn smut fungus)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Deaminates gamma-aminobutyric acid (GABA) to succinate-semialdehyde, which in turn is converted to succinate by the succinate semialdehyde dehydrogenase (By similarity). Not required for the utilization of GABA as nitrogen source.By similarity1 Publication

Catalytic activityi

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

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
