New and enhanced features have been added to the RCSB PDB resource:
Protein Feature View provides a graphical summary of how different annotations correspond to PDB entries. New options include visualization of information from the wwPDB Validation Report and a summary of expression tags, cloning artifacts, and other mismatches between the studied protein and reference UniProt sequence.
The Sequence Cluster Report option will list protein chains as grouped in clusters by sequence identity (100% to 30%). For example, the 90% sequence cluster groups protein sequences that are at least 90% identical. This report option also includes UniProt Recommended and Alternative Names, Gene Name, and Macromolecular Name and Synonyms.
A new drill-down option identifies the most common UniProt molecule names represented in the PDB.
Pfam annotations have been updated to the latest version (28).
Options for chain-based analysis have been added to facilitate accurate searching and reporting.
