pCstA+RBS

This BioBrick comprises a ligation of the registry parts for the promoter PcstA (BBa_K118011) and the RBS (BBa_B0034).

The PcstA promoter is cAMP activated. Under low glucose concentrations, there is increased activity by adenylate cyclase. This results in cAMP binding to the cAMP receptor protein, and activating the promoter for downstream expression (more information on this part can be found on its registry page here).

This promoter has been ligated to an RBS as an intermediate step of ligations. By adding a coding region followed by terminator after this part, one would create a glucose sensitive functional unit.

Usage and Biology

Imperial iGEM 2009 used the promoter as part of the autoinduction module of the project. By using minimal media combined with a secondary carbon source and limited glucose supply, the team aimed to characterise a time delay during cell growth after which the promoter will be activated.
