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. 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 in some of our Psicose biosensors (BBa_K2448030 and BBa_K2448031) and the results shows that PsiR behaved as predicted under and without induction.
