This entry represents the C-terminal domain found in CecR (regulator of cefoperazone and chloramphenicol sensitivity), previously known as YbiH. CecR has been shown to control sensitivity to cefoperazone and chloramphenicol through regulating the transcription of the cecR-ybhGFSR operon and the rhlE gene [1].	Domain
