Abstract
Using the theoretical model of DNA curvature, we have studied about 112 different E. coli promoters with a view to obtain some common super structures associated with them. Out of the 112 promoters analyzed by theoretical gel electrophoresis permutation about 66 of them have their minima lying between the - 10 and the -35 region. The analysis of the bases at the minima reveals strong structural similarities. The differences can account for the varying strengths of the promoters as well as for different degree with which the RNA polymerase binds to these regions. The effects of mutation in each of these 112 promoters and their changes in curvature dispersion have also been evaluated.
