p25-E5501: GFP under control of medium constitutive promoter

This part consists of E5501 (GFP with medium ribosome binding site) under the control of p25, a medium constitutive bacterial promoter. Its intended use is to serve a promoter-reporter construct in lactic acid bacteria. p25 was initially identified in a promoter probe survey of the Streptococcus thermophilus genome, alongside weaker promoters p8 and p20.

We used p25 as a candidate promoter to drive gene expression in both Streptococcus thermophilus and E. coli. Quantification of p25 using GFP in E. coli revealed promoter strength on par with medium Anderson promoters (30.8% as strong as J23100, 43.7% as strong as J23101, 130% as strong as J23106).
