Histograms of net charges and dipole moments for unique protein chains in the PDB. (A) Histogram of the distribution of net charges for 14 053 unique chains, prepared using KalaidaGraph (23). The distribution for 11 981 biological units is very similar. (B) Histogram of the distribution of dipole moments for 14 053 unique chains. For clarity, the histogram had to be truncated at 4000 D, even though the distribution continues to almost 5600 D. Only 14 chains have dipoles larger than 4000 D. The distribution for 11 981 biological units is very similar. (C) Histogram of the distribution of the net charge per atom for unique chains. The distribution for biological units is very similar. (D) Histogram of the distribution of net dipole moment per atom for unique chains. For clarity, the histogram had to be truncated at 2 D, even though the distribution continues almost up to 25 D. The distribution for biological units is very similar.
