Modelling
Promoter pBAD Strong
We decided to utilise the pBAD strong promoter (K206000), which was created by the British Columbia iGEM 2009 team as a mutagenized form of the naturally occurring pBAD promoter. The modelling was based upon and used references pertaining to the pBAD promoter, also known as the 'ara operon'. pBAD and pBAD strong are both arabinose-inducible promoters.
In the absence and presence of arabinose, the pBAD promoter acts as a repressor and an inducer respectively. The gene products of pBAD in Escherichia coli allow the cells to take up and catabolize L-arabinose, a five-carbon sugar.
pBAD’s very basic structure is depicted below:
