Transcription factor FadR from the GntR protein family regulates the fatty acid utilization genes in Gammaproteobacteria. It was originally characterized in Escherichia coli as a repressor of the fatty acid degradation genes, and later it was shown to act as an activator of the fatty acid biosynthesis genes fabA and fabB. The comparative genomic approach was used to reconstruct FadR regulons in Enterobacteria and other Gammaproteobacteria [18820024]. In some lineages of Gammaproteobacteria, FadR co-exists with another regulator of fatty acid degradation genes, PsrA (TetR family).
