Design Notes

The wt sequence for the lac operon regulatory region was taken from Kalnins A. (1993) [GenBank accession no. J01636]. Within the CAP binding site, bases -66 (G) and -55 (C) of the wt binding region were substituted with A and T respectively to prevent binding of the CAP protein at low glucose concentrations. The wt -10 promoter sequence was also mutated from TATGTT to TATAAT in order to allow σ factor (RpoD) to bind without relying on further activation by the CAP protein (Reznikoff et al., 1978).
