Part:BBa_K191003

Promoter Lac I - RBS - LovTAP - Term

Part BBa_K191003 codes for the hybrid protein LovTAP. This hybrid protein has a light-sensitive domain ( Lov means light, oxygen, voltage)and a regulatory domain (like Trp repressor). The fused protein allows transmission of the conformational change induced by light (on the light-sensitive domain) to the DNA-binding domain. The latter would then result in an increase or decrease of the regulatory domain's affinity for its DNA binding site.

Usage and Biology

In order to be able to test the efficiency of the fused protein LovTAP, its expression is induced by IPTG ( thanks to the LacI promoter). Two other parts were also constructed as the read out systems of LovTAP : BBa_K191004 and BBa_K191005

All three parts together gives the following system, where LovTAP activities can be measured through RFP fluorescence intensity
