Design Notes

tsPurpleLAA is composed of a ribosomal binding site, tsPurple (a purple chromoprotein which functions as a reporter), and LAA (a fast degradation tag). tsPurpleLAA is intended to be assembled with pLambdaR-LacI (which is the promoter and regulatory system) and r0011ClpXPCI (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 tsPurpleLAA 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 LAA deg tag and degrade the tsPurple protein. Since LAA is a fast degradation tag, so tsPurpleLAA should have the highest levels of degradation seen. 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 tsPurpleLAA is not expressed unless it is assembled with pLambdaR-LacI (BBa_K1911000). The protease complex of ClpX and ClpP is from part (BBa_K1911001).
