PDB Protein Structure Agent

The PDB Agent provides access to the RCSB Protein Data Bank for structural biologists and computational chemists. Search 200,000+ experimentally determined structures by text, sequence, or structural similarity, download coordinates in PDB/mmCIF formats, and retrieve quality metrics for structure-based drug discovery. **Key Capabilities:** - Text and attribute-based searches - Sequence similarity searches - Structure similarity searches - Coordinate file downloads (PDB, mmCIF, BinaryCIF) - Metadata and quality metrics - Batch operations **Database Connections:** - RCSB Protein Data Bank (REST API) - 200,000+ experimental 3D structures — rcsb.org - Structure Search (REST API/Python) - Find proteins by text, sequence, or 3D similarity — rcsb-api - Coordinate Downloader (HTTP) - Retrieve PDB, mmCIF, and BinaryCIF files - Quality Metrics (REST API) - Access resolution, R-factors, and validation reports
