Packing geometries

The significance of any clustering in the contacts is assessed with reference to packing-geometries generated at random from 20 trials of 2753 randomly-chosen and randomly placed contacts.

The clusters

The pairs of plots below show a representative sidechain for each cluster.

In the first plot of each pair the sidechains are shown as ball-and-stick models; in the second plot the van der Waals surfaces are superimposed as wire-cage contours. The reference sidechain is shown in purple while the cluster representative is shown in orange. Click on the first plot to get a magnified view, including the other cluster members.

Each cluster representative is chosen to have a r.m.s.d. of <1.5 Angstroms from all other members of the cluster. The standard deviation shows how significant the clustering is, when compared with a randomly-generated contact distribution for these two sidechains.

The ticks on the back walls in the plots correspond to distances of 1 Angstrom.
