Pathway Description
Operon: Nucleotide and Deoxyribonucleotide Catabolism III
Escherichia coli
Protein Pathway
The nucleotide and deoxyribonucleotide operon is a polycistronic operon consisting of the genes DeoC, DeoA, DeoB and DeoD. This operon's transcription is activated by Fis DNA-binding transcriptional dual regulator binding to a -102 bp site off the promoter. This operon can also be activated by having CRP-cAMP DNA-binding transcriptional dual regulator binding either to -93.5 or -40.5. The repression of the operon's transcription can be controlled by multiple sites upsteam the promoter: - DeoR (DeoR DNA-binding transcriptional repressor) -887, -309, -8 for promoter deop2 and -609, -8, and 269 for promoter deop1 - CRP-cAMP DNA-binding transcriptional dual regulator binding at -93.5 for promoter deop2 - CytR (CytR DNA-binding transcriptional repressor) -87.5, -70.5, -61 for promoter deop2 -ModE-MoO42- DNA-binding transcriptional dual regulator -35 for promoter deop2
