== Function ==
[https://www.uniprot.org/uniprot/GABR_BACSU GABR_BACSU] Activates the transcription of the gabTD operon. Is also a repressor of its own expression, both in the presence and absence of GABA. Binds specifically to the DNA region overlapping the -35 region of the gabT promoter and the -10 and +1 regions of the gabR promoter. Principally regulates the utilization of gamma-aminobutyrate.<ref>PMID:12123465</ref> <ref>PMID:15223311</ref>
