Ser-Met distribution
Ser-Met distributionNumber of Ser sidechains in dataset 28561 ( 5.9% )
Number of Met sidechains in dataset 8855 ( 1.8% )
Total number of Ser-Met contacts 1245
* 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 1243 randomly-chosen and randomly placed contacts.
Cluster 1. Size: Mean 12.90 St.dev. 1.14
Cluster 2. Size: Mean 12.10 St.dev. 0.99
Cluster 3. Size: Mean 11.55 St.dev. 0.74
Cluster 4. Size: Mean 11.25 St.dev. 0.62
Cluster 5. Size: Mean 10.80 St.dev. 0.60
Cluster 6. Size: Mean 10.50 St.dev. 0.50
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.
