The glucuronate pathway operon is a bicistronic operon consisting of the genes uxuA and uxuB. The transcription of this operon is activated by CRP-cAMP DNA-binding transcriptional dual regulator binding to -57.5 or -142.5 bp off the promoter. The transcription of the operon can be repressed by multiple means: -UxuR (UxuR DNA-binding transcriptional repressor) binding -159.5 or -53.5 off the promoter -ExuR (ExuR DNA-binding transcriptional repressor) binding to -159.5 or -53.5 off the promoter -OxyR (OxyR DNA-binding transcriptional dual regulator) binding to -54 or -32 off the promoter
