Composite

Part:BBa_K1132020

rbs-YF1-rbs-FixJ-term-pFixK2-mRFP1

This composite part can be used for a blue light sensitive system. It is built with 4 preexisting parts : rbs-YF1-rbs-FixJ (BBa_K592016) with a terminator (BBa_B1010) and followed by FixK2 (BBa_K081014)-rbs-mRFP1-term (BBa_K592006). Rbs-YF1-rbs-FixJ is a regulatory protein working with the promotor FixK2. In darkness, YF1 is phosphorylated and gives its phosphate group to FixJ. Once phosphorylated, FixJ can bind to FixK2 promoter and actives it. In light, FixK2 promoter can't work.
A final construction was made with a constitutive promoter (Bba_J23116) but this promoter seems to weak to generate enought copies of YF1-FixJ to activate FixK2.
Adding a strong promoter before this biobrick can improve the system.
