Ala-Glu distribution
Ala-Glu distributionNumber of Ala sidechains in dataset 40341 ( 8.4% )
Number of Glu sidechains in dataset 32564 ( 6.7% )
Total number of Ala-Glu contacts 2825
* 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 2808 randomly-chosen and randomly placed contacts.
Cluster 1. Size: Mean 78.10 St.dev. 3.10
Cluster 2. Size: Mean 75.85 St.dev. 2.63
Cluster 3. Size: Mean 72.90 St.dev. 1.51
Cluster 4. Size: Mean 70.70 St.dev. 1.85
Cluster 5. Size: Mean 68.70 St.dev. 2.69
Cluster 6. Size: Mean 67.25 St.dev. 2.38
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 1. Size 143 ( 20.96 st. devs. from mean )
Cluster 2. Size 120 ( 16.77 st. devs. from mean )
Cluster 3. Size 84 ( 7.34 st. devs. from mean )
