Operon: Glucuronate Pathway
Escherichia coli

Cellular Response
Created: 2015-11-10
Last Updated: 2025-05-31
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
