PDB file
Also written: Protein Data Bank file
A file format storing atomic coordinates of molecules, often used for proteins, to visualize their 3D structure.
A PDB file is a text file that describes the 3D arrangement of atoms in a molecule. Think of it like a blueprint for a molecule, showing where each atom is located in space.
These files are most commonly used for biological molecules like proteins. Scientists use them to study how proteins are shaped, which helps them understand how they work and how to design drugs that interact with them. You can open a PDB file with special software to see a 3D model of the molecule.
PDB (Protein Data Bank) files are a standard format for representing the atomic coordinates of biological macromolecules. Each record contains information about the atomic positions, residue sequences, and crystallographic structure factors. The format is primarily used for visualizing and analyzing protein and nucleic acid structures derived from experimental methods like X-ray crystallography and NMR spectroscopy.
While the format originated for proteins, it is also used for other biomolecules. The data is human-readable text but is typically processed by molecular visualization software. Its widespread adoption makes it a crucial data exchange format in structural biology.
OpenAI's integration of Rosalind Workbench with ChatGPT allows scientists to use AI for analyzing biological data, including structures stored in PDB files. This highlights the growing trend of applying AI to complex scientific domains, making specialized data formats like PDB more accessible.

Questions people ask
- What kind of information is in a PDB file?
- A PDB file contains the 3D coordinates of atoms in a molecule, along with information about the molecule's identity and how the structure was determined.
- Can I open a PDB file with a regular text editor?
- Yes, a PDB file is a plain text file, so you can open it with any text editor. However, it will be difficult to understand without specialized molecular visualization software.
