1D89

1D89 is the identifier for a macromolecular structure in the Protein Data Bank (PDB). The PDB is a public database that archives 3D structural data of biological macromolecules, determined experimentally by techniques such as X-ray crystallography, nuclear magnetic resonance (NMR), or cryo-electron microscopy (cryo-EM). A PDB entry associated with the code 1D89 would include atomic coordinates, an associated sequence, information about the macromolecule(s) and any bound ligands or ions, along with metadata about the experiment, authors, and publication if available. Structural data typically include the resolution, R-factor or R-free, the method used, and details about the biological assembly and symmetry.

The code 1D89 can be searched in the PDB to retrieve the full entry, which would present the 3D coordinates that researchers use to analyze molecular structure, conformational changes, active sites, and interactions with ligands or other proteins. The entry may also link to related literature and to other related PDB entries.

In the context of structural biology, 1D89 represents one data point among tens of thousands used to understand molecular function at atomic resolution. Access to 1D89, like other PDB codes, is provided to researchers and educators worldwide, supporting computational modeling, visualization, and hypothesis generation.
