Part:BBa_K1744001:Design
P1U8-amilCP-kanR
Design Notes
The amilCP chromoprotein synthesis could be improved for the blue color to be visible in single copy faster. It has been of great concern through-out all the project and that is why we have put the strongest combination of promoter and RBS we have found to be well characterised. Still, expression in single copy is not so intense. In our case, amilCP can still be useful as a marker for plasmid background detection during recombineering experiment. Using only the kanamycin marker for recombineering, the blue colonies would represent plasmid transformants and not good recombinants. This use is good for us though, since background is a great concern in recombineering techniques, where screening can be long.
Sources
The part was constructed using a kanamycin resistance gene from plasmid pOK12 (available commercially) and amilCP from BBa_K592009. The promoter and RBS P1U8 were synthesized and come from Mutalik et al. (Nature 2013).
