Effect of base pair substitution in λ-PR promoter. (A) The sequence of λ-PR promoter. The red-colored bases are the −35 element and the blue-colored bases are the −10 elements. (B) Binding isotherm of E. coli RNA polymerase with wild-type λ-PR promoter using fluorescence anisotropy at 4°C. (C) Binding isotherm of dAT-20 oligomer duplex under identical conditions. (D) ΔΔG values of single-base pair mutants of λ-PR promoter.
