Note(s): | When phenylalanine interacts with the TyrR protein, a dimer of this protein binds to a strong TyrR box located 64.5 bp upstream of the tyrPp1 promoter and activates the transcription of the tyrP gene Yang J,2004 It has been shown that the C-terminal domain of the RNA polymerase is involved in the activation of the tyrPp1 promoter by theTyrR protein Lawley B,1995 On the other hand, when tyrosine and ATP interact with the TyrR protein, the transcription of the gene is repressed through the binding of a TyrR hexamer to a weak TyrR box located 41.5 bp upstream of the tyrPp1 promoter and to the strong TyrR box mentioned earlier. In the repression process, the binding of RNA polymerase to the tyrPp promoter is blocked by TyrR hexamer Yang J,2004 |

Note(s): |
1The TyrR-binding site at position -64.5 from the promoter is a strong TyrR box that is involved in the activation and repression of tyrP gene transcription. The TyrR protein with phenylalanine only binds to this site to activate transcription, whereas the protein with tyrosine binds to this and another weak site (-41.5 from the promoter) to repress the transcription Yang J,20041The TyrR-binding site at position -64.5 from the promoter is a strong TyrR box that is involved in the activation and repression of tyrP gene transcription.
