Distribution of Θ1 angles and RH⋯A distances for all models in the PDB at resolutions of better than 1.5 Å (2941 models) and worse than 4.0 Å (4712 models). The number of hydrogen bonds considered in the high-resolution set are 356 797, 109 233 and 1 038 363 for α-helices, β-sheets and total, respectively. The total numbers of hydrogen bonds considered in the low-resolution set are 6 676 005, 1 191 779 and 13 480 683 for α-helices, β-sheets and total, respectively. |
