lacI pL + RBS + RcsA + TT

Our goals is to have each cell produce enough colonic acid to protect itself from the harsh acidic conditions of the stomach. We placed RcsA, RcsB, and a combination of the two under a IPTG inducible promoter to test both quantity of colonic acid produced and cell survivability. You can see our data by downloading the associated .zip file for any of these three devices: BBa_K318500(RcsA), BBa_K318501(RcsB), BBa_K318502(RcsA+RcsB).

Usage and Biology

RcsA is a transcription factor that is know to be a positive regulator of capsular polysaccharide synthesis. Along with transcription factor RcsB, these two transcription factors form a heterodimer that is know to activate around 19 genes related to colonic acid synthesis.
