Promoter Pcar [BBa_K861171] is a glucose responsive promoter created by WHU-China in 2012. Pcar promoter region was de novo designed with overlapping of CRP and RNA polymerase binding site. The initiation of transcription by RNA polymerase may be hindered by the binding of CRP, which occurs at the formation of cAMP-CRP complex in the low concentration of glucose. In other words, when the amount of glucose is high enough, Pcar would be turned on after the leaving of CPR due to the low concentration of cAMP, and vice versa. | Promoter Pcar [BBa_K861171] is a glucose responsive promoter created by WHU-China in 2012.

Pcar-RBS-PhlF-T/pSB1C3
Promoter Pcar [BBa_K861171] is a glucose responsive promoter created by WHU-China in 2012. Pcar promoter region was de novo designed with overlapping of CRP and RNA polymerase binding site. The initiation of transcription by RNA polymerase may be hindered by the binding of CRP, which occurs at the formation of cAMP-CRP complex in the low concentration of glucose. In other words, when the amount of glucose is high enough, Pcar would be turned on after the leaving of CPR due to the low concentration of cAMP, and vice versa.
PhlF repressor system contains the repressor PhlF [BBa_K1725041] and the PhlF repressible promoter [BBa_K1725001] created by Glasgow in 2015. PhlF could repress GFP fluorescence intensity by 83-fold according to the study of Glasgow’s work.
Cloning
Pcar-RBS-PhlF was amplified from RBS + PhlF repressor + terminator (BBa_K1725041) using a primer with Pcar-RBS (B0032) sequence. The PCR product was ligated to pSB1C3 cut by XbaI and PstI.
Function
Repressor PhlF can be dose-dependently expressed in an increasing concentrations of glucose. According to teams WHU-China 2012 & NCKU_Tainan 2016, the promoter, Pcar, is glucose responsive.
