1EB7

1EB7 is the four-character alphanumeric identifier assigned by the Protein Data Bank (PDB) to a specific macromolecular structure entry. PDB IDs are used to catalog experimentally determined three-dimensional structures of biological molecules, most commonly proteins and nucleic acids, solved by techniques such as X-ray crystallography, nuclear magnetic resonance spectroscopy, or cryo-electron microscopy. Each entry consolidates structural coordinates with experimental details, supporting information, and literature references.

An entry typically includes a header with deposition date and authors, information about the biological assembly, the experimental method and conditions, and quality indicators such as resolution or map statistics. The structural model(s) consist of coordinates for one or more chains, with chain identifiers, residue numbers, and information on standard or nonstandard residues. The entry may also list bound ligands, cofactors, metal ions, solvent molecules, and any alternate conformations. Cross-references link the structure to related databases and literature, including UniProt, GenBank, and PubMed.

Access and formats: 1EB7 can be retrieved from the Protein Data Bank website. Data are provided in standard formats, such as PDB and mmCIF, with options to download coordinate files, ligand data, and validation reports. Users can view the model online or download it for visualization and computational analysis.

Interpretation and reliability: The quality of a PDB entry depends on the experimental method and resolution. Entries include validation metrics and quality indicators, such as resolution, R-free, and B-factors. Researchers assess these indicators to determine the reliability of structural features for further study.

Context and use: PDB entries like 1EB7 serve as reference points for studying molecular function, interactions, and mechanisms, supporting research across structural biology, biochemistry, and drug design.
