PDB file format

A PDB (Protein Data Bank) file format is a standardized text file that records the 3D structure of molecules like proteins and DNA. It contains detailed information about each atom’s type, position (coordinates in space), and how atoms are connected, allowing scientists to visualize and analyze molecular structures. The format organizes data into specific lines with labels, making it a consistent way to share structural data across research and simulation tools. Essentially, a PDB file acts as a blueprint that captures the precise spatial arrangement of molecules essential for understanding their function.
