Macromolecular structure databases are crucial for crystallographers. Analysis of the Protein Data Bank (PDB) reveals data inconsistencies, highlighting the need for improved information management in structural biology.

Area of Science:

  • Structural biology
  • Bioinformatics
  • Crystallography

Background:

  • Macromolecular structure databases are essential tools for crystallographers.
  • Numerous databases have been developed to aid in protein structure analysis.
  • The Protein Data Bank (PDB) is a primary repository for structural data.

Purpose of the Study:

  • To review the evolution and features of macromolecular structure databases.
  • To analyze the self-consistency of the Protein Data Bank (PDB) corpus.
  • To identify trends and challenges in structural data management.

Main Methods:

  • Summary of features of existing macromolecular structure databases.
  • Detailed discussion of the PDB+ database, including current and obsolete structures.
