Trp-Asp distribution
Trp-Asp distributionNumber of Trp sidechains in dataset 7118 ( 1.5% )
Number of Asp sidechains in dataset 27965 ( 5.8% )
Total number of Trp-Asp contacts 1302
* 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 1302 randomly-chosen and randomly placed contacts.
Cluster 1. Size: Mean 23.10 St.dev. 1.22
Cluster 2. Size: Mean 21.50 St.dev. 1.02
Cluster 3. Size: Mean 20.65 St.dev. 0.91
Cluster 4. Size: Mean 19.80 St.dev. 0.68
Cluster 5. Size: Mean 19.40 St.dev. 0.80
Cluster 6. Size: Mean 18.65 St.dev. 0.57
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.
