Design Notes
tsPurpleDAS is composed of a ribosomal binding site, tsPurple (a purple chromoprotein which functions as a reporter), and DAS (a moderately fast degradation tag). tsPurpleDAS is intended to be assembled with pLambdaR-LacI (BBa_K1911000),which is the promoter and regulatory system, and pLac-ClpXP-CI (BBa_K1911001),which is the non-lysosomal protease. The terminator is located at the beginning of pLac-ClpXP-CI. When fully assembled, p-lambda-r LacI transcribes tsPurple and LacI represses pLac, preventing transcription of ClpXP-CI. Upon induction with IPTG, LacI binds to IPTG which prevents repression of pLac. Therefore, ClpXP-CI is transcribed; ClpXP should recognize the DAS deg tag and degrade the tsPurple protein. The ensuing levels of expression could then be compared to that of BBa_K2353000 (tsPurple without a deg tag) to see the relative level of degradation experienced. IMPORTANT NOTE: The promoter and terminator are both part of different parts, which means tspurple is not expressed unless it is assembled with pLambdaR-LacI (BBa_K1911000). The protease complex of ClpX and ClpP is from part (BBa_K1911001)
