Usage and Biology

This is a composite part designed as a report protein sequence for use in Lactococcus lactis. The promoter is a mid-range promoter 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 codon optimized for Lactobacillus reuteri and biobricked according to standard 25, and a popular double-stop terminator. 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 cell and two other similar constructs (see Figure 1).
