Blast

Blast this sequence against all of PDB Archive.

Rank

In each cluster, the chains are sorted (i.e. ranked) according to the following criteria (in this order):

1. A simple quality factor, calculated as
   1/resolution - R-value
2. Deposition date (newer structures have higher ranks)
3. Alphabetically

This ranking has the following implications:

• Higher quality structures (better resolution, lower R-value) are preferred.
• Structures determined by X-ray crystallography are preferred over NMR structures.

Cluster ID / Name

The internal number of the sequence cluster used for unique identification.

Structural variation in clusters

The identification of similar sequences in this report is based on clustering as described here.

The PDBFlex database explores the intrinsic flexibility of protein structures by analyzing structural variations of the same protein across the archive. This allows for the easy identification of regions and types of structural flexibility present in a protein of interest. Structures of protein chains with identical sequences (sequence identity > 95%) are aligned, superimposed and clustered.
