* Non-random at 95.0% confidence level.
** Non-random at 97.5% confidence level.
*** Non-random at 99.0% confidence level.
**** Non-random at 99.5% confidence level.
The significance of any clustering in the contacts is assessed with reference to packing-geometries generated at random from 20 trials of 2495 randomly-chosen and randomly placed contacts.
Cluster 1. Size: Mean 77.55 St.dev. 3.32
Cluster 2. Size: Mean 73.80 St.dev. 2.34
Cluster 3. Size: Mean 70.90 St.dev. 2.05
Cluster 4. Size: Mean 68.75 St.dev. 1.84
Cluster 5. Size: Mean 66.55 St.dev. 1.75
Cluster 6. Size: Mean 65.20 St.dev. 1.75
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.

Cluster 3. Size 129 ( 28.38 st. devs. from mean )
Cluster 4. Size 80 ( 6.11 st. devs. from mean )
