A thin slice through an all-atom contact kinemage showing the van der Waals interactions of Pro203 and neighbouring atoms in Zn elastase at 1.5 Å resolution (PDB file 1EZM). Contact dots are colour-coded by the gap between atoms: blue for wider gaps (up to 0.5 Å), green for closer fit and yellow for slight overlap (but still favourable). Note the extensive contact and the interdigitation of hydrogen atoms. White markers show the last two points picked (Pro Hg1 and one of its contact dots), while the distance between them and the identity of the last one are shown at bottom left. Hydrogen atoms are from REDUCE, contact dots are from PROBE and the display is done in MAGE.
