p32-E5501: GFP under control of strong constitutive promoter

This part consists of E5501 (GFP with medium ribosome binding site) under the control of p32, a strong constitutive bacterial promoter. Its intended use is to serve as a promoter-reporter construct in lactic acid bacteria. p32 is used as a promoter in expression vectors functioning within Streptococcus thermophilus

We used p32 as a candidate promoter to drive gene expression in both Streptococcus thermophilus and E. coli. Quantification of p32 using GFP revealed promoter strength on par with strong Anderson promoters (81% as strong as J23100, 115% as strong as J23101).

Figure 2: Mean fluorescence values for E5501 under the control of various promoters. Red represents S. thermophilus promoters, blue represents Anderson family promoters. Error bars represent standard deviation for each set of samples. Promoters are ordered according to their strength when expressing I13500.
