1DBB

1DBB is a four-character alphanumeric code that serves as an identifier in several technical contexts. The most widely recognized use is as a Protein Data Bank (PDB) entry identifier.

In this context, 1DBB designates a single deposited macromolecular structure. PDB entries contain coordinates for the atoms in the molecule(s) and metadata including the experimental method used to determine the structure (often X-ray crystallography or NMR), the resolution, information about the source organism, polymer chain identifiers, and links to related literature. The precise biological interpretation and function of the structure are described in the PDB record and associated publications.

Outside structural biology, 1DBB may appear as a model or part number in various catalogs and product lines, such as electronics, mechanical components, or software releases. Because such codes are not standardized across industries, the same sequence of characters can refer to different items in different contexts.

Users seeking to identify what 1DBB refers to should locate the context in which the code appears, and consult the corresponding database or catalog record. For PDB entries, the RCSB PDB or Protein Data Bank in Europe mirrors provide details and downloadable files.
