The scientific name associated with this taxonomy code aggregated by the NCBI Taxonomy Database. This name corresponds to the taxonomy identifier assigned by the PDB depositor, and includes natural, engineered, and synthetic source organisms.

A parent scientific name in the NCBI taxonomy hierarchy of the source organism assigned by the PDB depositor. For cellular organism this corresponds to a superkingdom (e.g., Archaea, Bacteria, Eukaryota). For viruses this corresponds to a clade (e.g. Adnaviria, Bicaudaviridae, Clavaviridae). For other and unclassified entries this corresponds to the first level of any taxonomic rank below the root level.

PDB structures may contain multiple entities of different macromolecular types.

Distribution by structure resolution (?). Data shown include structures solved by X-ray crystallography or electron microscopy.

The year a structure entry was released in the PDB archive.

Enzyme Classification is based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB). EC (Enzyme Commission) numbers are assigned to PDB structures using UniProtKB/GenBank/KEGG/author-specified mapping.

Protein symmetry is calculated for all protein complexes in the PDB, and updated weekly.

The SCOP-e database aims to provide a detailed and comprehensive description of the structural and evolutionary relationships between all proteins whose structure is known. As such, it provides a broad survey of protein folds, detailed information about the close relatives of any particular protein, and a framework for future research and classification.
