pHLBA-I13500: GFP under control of strong constitutive promoter and strong ribosome binding site

This part consists of I13500 (GFP with a strong ribosome binding site) under the control of pHLBA, a strong constitutive bacterial promoter. Its intended use is to serve a promoter-reporter construct in lactic acid bacteria. pHLBA was initially identified in studies of Lactobacillus bulgaricus where it drives the expression of histone-like proteins. pHLBA is likely functional in all lactic acid bacteria.

We used pHLBA as a candidate promoter to drive gene expression in both Streptococcus thermophilus and E. coli. Quantification of pHLBA using GFP in E. coli revealed promoter strength on par with strong Anderson promoters (93% as strong as J23100, 132% as strong as J23101).
