pPsiR from Agrobacterium tumefaciens

This part is the promoter region (0.36 kb upstream) of the PsiR gene of Agrobacterium tumefaciens str. C58 (Atu4743)

pPsiR is predicted to be repressed by the PsiR transcription factor (BBa_K2448006) which is inhibited in the presence of D-Psicose [1].

Usage and Biology

Our team used this pPsiR promoter together with the Agrobacterium tumefaciens PsiR transcription factor (BBa_K2448006) to build a Psicose biosensor (BBa_K2448026). The results show that pPsiR is functional in E. coli and that it behaved as predicted under and without induction. 

Using the BPROM webserver [2], the predicted features of this promoter are:
Threshold for promoters -  0.20
Number of predicted promoters -      1
Promoter Pos:    299 LDF-  3.13
-10 box at pos.    284 tggtgcaat Score    40
-35 box at pos.    264 ttgcca    Score    61
Oligonucleotides from known TF binding sites:
    rpoD17:  TGCAATAA at position     287 Score -   5
