Transcription factors PsrA belong to the TetR protein family and control the fatty acid degradation in Proteobacteria. The PsrA regulon and its DNA-binding motif were discovered by application of the comparative genomic approach to the fatty acid degradation genes in the Shewanella lineage [21810205]. Then PsrA regulons were reconstructed in other taxonomic groups of Proteobacteria that possess an ortholog of the PsrA regulator [18820024]. The reconstructed PsrA regulons in different taxonomic groups showed the significant variability in their gene content.
