PDB-maps of 3DP-similarity space color-coded by (a) occupancy, (b) heavy atom count, (c) molecular volume occupancy (mvo), (d) percentage of hydrophobic atoms, (e) percentage of positively charged atoms, (f) percentage of negatively charged atoms. The color-coding is from blue (lowest values) to magenta (highest values). (g) PDB-map color-coded by nPMI values. The rod-like structures are red color; the spherical structures are green color; the disc-like structures are blue color. The maps were computed from 91,223 X-ray structures from the PDB downloaded in September 2014, considering in each case the biological assembly as defined by the author
