A zoom upstream of the E. coli K12 MG1665 rrnB operon. The three outer-most lanes show SIDD at three superhelix densities of sigma=-0.055, −0.045, and −0.035. The lower free energy required to melt the helix can be observed near the UP element of P1, for the SIDD lane at sigma = −0.045. The atlas is available for zooming on the supplemental data section.
