Part:BBa_K1820019
CP44_RBS_mCherry(Lr)_Terminator
Usage and Biology
- This has only been tested in E. coli thus far.
This is a composite part designed as a report protein sequence for use in Lactococcus lactis. The promoter is a high-range promoter, part BBa_K1033225 from the 2013 Uppsala team, from Peter Ruhdal Jensen and Karin Hammer's library of synthetic promoters for Lactococcus lactis followed by a popular ribosome binding site (Elowitz 1999), an mCherry fluorescent protein, part BBa_K1033250 from the 2013 Uppsala team, codon optimized for Lactobacillus reuteri and biobricked according to standard 25, and a popular double-stop terminator. We further characterized this promoter with the addition of a fluorescent protein. Although it was designed for L. lactis, it has displayed function in Escherichia coli as well. There are indications that the promoter is functional in a large number of prokaryotic organisms. As such, it is likely that this construct will be functional in a variety of prokaryotic organisms.
We created and tested this construct in Escherichia coli in the pSB1C3 plasmid. It was tested for fluorescence relative to non-transformed E. coli cells (see Figure 1).
This part improves upon CP44 (https://parts.igem.org/Part:BBa_K1033225) by the addition of a RBS, fluorescent protein, and a terminator, as well as further characterization of the promoter.
