Searching with a protein structure identifier

By searching for a protein structure identifier with the quick search or by clicking on it in the search results list, you’ll be redirected to the InterPro structure page.

The structure page, like the protein page, is also similar to the sequence search result page, but with extra information, as shown in Figure 21. This contains information on the name of the structure in PDBe, its identifier, its resolution, chains and release date. On the right side, a link to the structure page in the Protein Data Bank in Europe is available.

On the side menu, ‘Entries‘ and ‘Proteins‘ list all the InterPro entries and UniProtKB proteins where the structure is found.

There is also a 3D structure viewer, where you can interact with the structure (e.g. turn, zoom…) and select a member database signature or an InterPro entry to visualise which part of the structure it matches.

For each chain in the structure, a protein sequence viewer shows the secondary structure information, Genome3D domain predictions, and the InterPro entries and member database signatures overlapping the chain.
