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-aeBlue/pSB1A3
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.
Cloning
Pcar-RBS-aeBlue was amplified from CP29-RBS-aeBlue (BBa_K1033280) using a primer with Pcar-RBS (B0034) sequence. The PCR product was ligated to pSB1A3 cut by XbaI and PstI.
Function
aeBlue 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.
