Note(s): Gavigan et al. (1999) and Perini et al. (1996) showed that CytR binds in tandem in the regulated intergenic region |CITS:[10347150] [8969182]|. On the other hand, in 1997, Pedersen and Valentin-Hanses showed that CytR binds to octamer repeats, GTTGCATT in either the direct or inverted orientation and preferably separated by 2 or 3 bp |CITS: [9155036][9466254]|. For this reason the length of the CytR DNA-binding site is variable.
However, footprinting analyses showed that the dimers of CytR are flanked or sandwiched by two dimers of CRP |CITS:[8596434]|. Thus, the binding sites of CytR located in this region were assigned by the curator in agreement based on similarity to the consensus sequence and on the data from the footprinting assays and mutational evidence |CITS:[ 8596434][1327747][20000490][9155036][2170326][12391883]|.
The repressor CytR and the activator CRP, two dimeric proteins, interact to form a complex repressor nucleoprotein in the intergenic region. When only CRP is bound to this promoter, it functions as an activator, and then, when CytR binds to DNA and to CRP, the activation is repressed because CytR masks an activating region of CRP that otherwise would contact the RNA polymerase to activate transcription |CITS:[8596434][8736525][10766824]|. The CytR protein cannot act alone; the synergistic DNA binding is increased by direct interaction with CRP |CITS:[8596434][1962841][2170326][1649947]|. At times CytR also repositions CRP to alternative DNA-binding sites that are not functional for activation |CITS:[ 8736525]|.
