Advanced CcaS with PAS domain knocked out
CcaS is a protein in CcaS-CcaR two-component system, which is sensitive to green light and red light. CcaS is located on the cell membrane and when it senses the existence of green light or red light, it will experience autophosphorylation and thus phosphorylate the downstream CcaR, and CcaR will bind to specific promoter to activate gene transcription. Typically, gene will be activated under green light and repressed under red light, but this advanced CcaS with PAS domain knocked out has reverse effect, gene will be repressed under green light and activated under red light. In our project, this advanced two-component system is used as a switch to sense different light and turn on the gene to produce PHB.
