Design Notes

PfadBA-RFP contains two parts (1)fatty acid-dependent promoter(pfad) and ribosomal binding site(RBS) (2)mRFP, a red fluorescent protein. The promoter pfad acts as a switch of downstream protein expression, and is regulated by the fatty acid-dependent promoter, FadR. mRFP plays a role as a reporter that indicates the expression or efficiency of the promoter. In the absence of fatty acids, FadR binds at a site downstream of the pfad promoter and represses transcription. When long chain fatty acids become available, they bind to FadR, and elicit a conformational change that releases the protein from DNA, thus removing the repression. In our part, FadR is constitutively expressed and could be repressed by adding oleic acid(a long-chain fatty acid), releasing the FadRs and thereby expressing mRFP.
