<p> Members of this protein family belong to the LuxR transcriptional regulator family, and contain both autoinducer binding (<db_xref db="INTERPRO" dbkey="IPR005143"/>) and transcriptional regulator (<db_xref db="INTERPRO" dbkey="IPR000792"/>) domains. Members of this family only occur adjacent to the gene hchA (chaperone/aminopeptidase) and are found in only a few of the Gammaproteobacteria. </p> Transcription regulator LuxR, chaperone HchA-associated
