Part:BBa_K1943001

fwYellow, yellow chromoprotein reporter system (medium Promoter , weak RBS)

We successfully constructed eight plasmids with various pigment coding sequence, including eforRed, gfasPurple, Fw Yellow and SpisPink. Compared to the common used fluorescence protein such as GFP, RFP, chromoprotein is significantly more useful reporter gene. In our parts, the coding sequences of these pigments are all among 700bp long, and the expression efficiency is high according to the experiment results. We contributed this series of the chromoprotein plasmid for the reason that they have significant advantages to be used as backbones. The length of 700bp is easy to distinguish from the original backbone (around 2000bp) by gel electrophoresis when constructing new expression system. Additionally, this kind of backbones are superior because we are able to directly observe the expression results by using naked eyes. It will be much more convenient for the laboratory with limited conditions and also save our time. In the tests, the color of colonies were easy to recognize after 18 hours of incubation. Our plasmid can also be a substitute for Part:BBa_J04450, which kindly recommended to be used in plasmid construction by replacing the RFP gene. For the same reason, we provide these pigment sequence to make the construction process more efficiently. Sequence and Features
