New Ways to Explore Similar Proteins
The PDB archive contains many entries that are very similar:
Structures: Some structures were deposited to the PDB together at the same time using the RCSB PDB Group Deposition server. These collections of structures (e.g., structures with same protein/s, but different bound ligands) are assigned a Group Deposition ID that identifies the collection.
Polymer Entities: Multiple PDB entries will contain polymer entities that share similar sequence identity (from 100% to 30%) as well as entities with the same UniProt Accession ID.
New features can be used to explore these "groups"
Grouped search results will highlight the number of structures in a group along with related information (example).
Access detailed documentation about this new feature for grouping redundant search results.
