PsiR from Sinorhizobium meliloti
This part is an E. coli codon optimized version of the PsiR found in Sinorhizobium meliloti (SMb20483).
Usage and Biology
PsiR is a predicted LacI family transcription factor with high affinity for D-Psicose [1]. This means that PsiR will prevent transcription of the regulated promoters in the absence of D-Psicose by binding the consensus sequences before the Transcription Start Site.
Our team used this transcription factor together with the Sinorhizobium meliloti pPsiA or pPsiR promoters (BBa_K2448014 and BBa_K2448015) to build two Psicose biosensors (BBa_K2448030 and BBa_K2448031). The results show that PsiR behaved as predicted under and without induction.
