New Ways to Explore Similar Proteins

"Group" summary pages and search results simplify exploration of PDB structures with similar sequence identity/UniProt ID or were deposited as part of the same study"Group" summary pages and search results simplify exploration of PDB structures with similar sequence identity/UniProt ID or were deposited as part of the same study

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"

  • Advanced Search return option can be used to detect similarity among search results and return data in "grouped" sets.

  • Group Summary Pages provide overviews of key features, properties, sequence alignments, and annotations of any predetermined or custom group.

  • Additionally, an interactive chart highlights the growth by year of unique UniProtKB sequences with known 3D structure.

    • Advanced Search

    Advanced Search options for displaying similar results as a "group" containing multiple entities/structures or as "representative" example.Advanced Search options for displaying similar results as a "group" containing multiple entities/structures or as "representative" example.

    Grouped search results will highlight the number of structures in a group along with related information (example).
