Pl-RBS-RFP-TT
Glucose detection device, which uses red fluorescence protein E1010 as a Reporter . PI promoter consists of overlapping consensus CRP-binding sites and consensus RNA polymerase binding site. Therefore, the steric hindrance between CRP and RNA polymerase will cause downstream genes to be repressed at a high concentration of CRP. In E.coli strains( e.g.DH5α and Bl21), a high concentration of CRP is presented when the glucose concentration is low, because, with the increasing adenylyl cyclase activity, the cAMP increase. cAMP will bind the cAMP receptor protein (CRP) which, in its bound form, can specifically bind the consensus CRP-binding site of Pl promoter , leading to repression of downstream genes. In contrast, when the glucose concentration is high, the adenylyl cyclase activity, cAMP, and CRP are decreased in the bound form . Consequently, an increased expression of downstream RFP E1010 can be a reporter gene as well as an indicator of the presence of glucose can be.
