This chart shows the fluorescence of GFP from module (BBa_K729008) that integrates the T7 RNA polymerase and T7 promoter in order to increase the expression of the reporter gene. Once the bacteria is exposed to carbon starvation stress, cstA promoter is activated, as a results it can be seen from the chart that GFP was expressed reaching higher accumulation in cultures with M9 media supplemented with less than 0.5% of glucose.

pCstA+RBS+T7RNAP+pT7+RBS+GFP+TT

This starvation sensitive device was used by the [http://2012.igem.org/Team:University_College_London UCL’s 2012 iGem team] to increase the expression of a reporter gene (GFP) under low glucose concentrations. During carbon starvation cAMP binds the cAMP receptor protein, the complex formed activates the expression of the downstream gene (T7 RNA polymerase), which promotes the expression of GFP under the control of the T7 promoter.

This device comprises the ligation of the parts (BBa_K729007) and (BBa_I746909).

BBa_K729008 integrates the T7 RNA polymerase and T7 promoter in order to increase the expression of the reporter gene. Once the bacteria is exposed to carbon starvation stress, cstA promoter is activated, as a results it can be seen from the chart that GFP was expressed reaching higher accumulation in cultures with M9 media supplemented with less than 0.5% of glucose.
