Arabinose sensor: the pBAD promoter
Overview
In order to make an analog biosensor, we need our traffic light to produce distinct, unique responses to a range of concentrations of an input. However, the Registry is lacking in variable strength inducible promoters. We designed two variants of the pBAD promoter, one weaker and one stronger than wild type, based on AraC binding experiments performed by Niland et al.
Above is a sequence alignment of our promoter variants with the wild type pBAD, truncated for space. For the full sequences, see our parts in the registry at (strong) and (weak).
Using these promoter sequences, we assembled XXX...
