PDB/UniProt Info retrieves sequence and structure annotations for Protein Data Bank (PDB) entries using a Web service provided by the RCSB PDB.
There are several ways to start PDB/UniProt Info, a tool in the Sequence category.
The top part of the dialog lists the chains of PDB files currently open in Chimera. One or more chains can be chosen with the left mouse button. Choosing a chain uses its PDB ID to look up information at the RCSB PDB. This information is fetched as an XML file, which can be cached and reused as needed depending on the Fetch preferences and whether the option to Ignore any cached data is checked. A dialog will appear for entering the ID code if it cannot be determined automatically. If the chain does not correspond to an entry in the PDB, no information can be retrieved.
Clicking Show UniProt page will display the UniProt page (if any) for each chosen chain in a browser window. Not all PDB chains are annotated with a UniProt identifier, and a given PDB entry may contain both chains with and without UniProt identifiers.
For valid PDB entries, the bottom part of the dialog will show entry title, primary literature citation, structure determination method, source organism, and release date. One or more entries can be chosen in the bottom part of the dialog. Clicking Show PubMed page will display (in a browser window) the primary citation abstract at PubMed for each chosen entry.
