Pdb

Definition

PDB, or Protein Data Bank, is a comprehensive database that stores 3D structural data of proteins, nucleic acids, and complex assemblies. It serves as a critical resource for researchers in fields such as crystallography, molecular biology, and bioinformatics, enabling scientists to visualize and analyze the structures of biomolecules in detail.

5 Must Know Facts For Your Next Test
