pPsiA from Sinorhizobium fredii
This part is the promoter region (0.4 kb upstream) of the PsiA gene of Sinorhizobium fredii (NGR_b11530)
pPsiA is predicted to be repressed by the PsiR transcription factor (BBa_K2448007) which is inhibited in the presence of D-Psicose [1].
Usage and Biology
Our team used this pPsiA promoter together with the Sinorhizobium fredii PsiR transcription factor (BBa_K2448007) to build a Psicose biosensor (BBa_K2448028). The results show that pPsiA is functional in E. coli and that it behaved as predicted under and without induction.
