The average value was calculated over the three replicates. Numbers in brackets represent the SDs (calculated over the 303 frames per complex). Note that the ΔΔGbind corresponds to the difference between mutant and wild-type complexes, and as such, positive ΔΔGbind values mean that the mutation to alanine destabilizes the complex.
