4. INTRODUCTION
It is an online server.
It is an archive of experimentally determined 3D structure of
biological macromolecules.
Full name – RCSB – PDB.
RCSB - Research Collaboratory for Structural Bioinformatics.
PDB - Protein Data Bank.
It is a freely accessible, publicly available and open source for all
global community.
Web address / URL - https://www.rcsb.org/

5. WHAT IS PDB ?
• The Protein Data Bank is a database that stores three-dimensional
structural data of biological macromolecules, primarily focusing on
proteins and nucleic acids.
• It is a crucial resource in structural biology.
• It is the first open access digital data resource for all kind of biology and
medicine.
• It can be accessed by scientists, researchers, students, and anyone who
wants study the structure of biological macromolecules.

6. HISTORY OF PDB
The PDB was established in 1971 at Brookhaven
National Laboratory under the leadership of Walter
Hamilton.
After Hamilton's untimely death, Tom Koetzle began to
lead the PDB in 1973, and then Joel Sussman in 1994.
Led by Helen M. Berman, the Research Collaboratory
for Structural Bioinformatics (RCSB) became responsible
for the management of the PDB in 1998 in response to an RFP and a lengthy review
process.
 Three institutions were involved: Rutgers, UCSD/SDSC, and CARB/NIST.
Since then, it has grown into an international resource that is actively curated and
maintained.

12. STRUCTURE DETERMINATION TECHNIQUES
X-ray Crystallography: X-ray crystallography has been pivotal in revealing the
structures of numerous proteins and other biomolecules.
Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR is particularly useful for
smaller proteins and in cases where crystallization is challenging.
Cryo-Electron Microscopy (Cryo-EM): Cryo-EM has revolutionized structural
biology, allowing the determination of structures of large and complex
macromolecular assemblies.
Cryo-Electron Tomography (Cryo-ET): Cryo-ET is used to study cellular
structures, organelles, and large protein complexes within their native cellular
context.
Single-Particle Analysis (SPA): SPA is used to determine the structures of various
large protein complexes, including ribosomes, viruses, and membrane proteins.
Small-Angle X-ray Scattering (SAXS): SAXS is used to study the conformational
changes and shape of flexible biomolecules.

13. DATA FORMAT
PDBx/mmCIF - It is an extension of the Crystallographic Information
File (CIF) format
PDBML/XML – It plays a crucial role in advancing structural biology
research by providing a structured and machine-readable format for the
exchange and dissemination of data from the PDB.
Legacy PDB Format - It has been used since the inception of the Protein
Data Bank in the early 1970s and continues to be used alongside more
modern formats, such as PDBx/mmCIF and PDBML/XML.

14. APPLICATIONS
Drug Discovery
Structure-Function Relationship
Biological Research
Structural Genomics
Disease Research
Enzyme Engineering
Education and Training
Structural Bioinformatics
Protein Engineering

15. CONCLUSION
 Protein Data Bank is a repository of 3D structure of proteins & nucleic acids.
 It enables open access to the knowledge of 3D structures, functions & evolution of
biological macromolecules.
 Browsing on PDB is very easy and quick.
 The Protein Data Bank continues to be an invaluable tool for researchers
worldwide, enabling the exploration of the intricate structures and functions of
biological molecules and driving progress in the life sciences.
 Its ongoing expansion, improved data curation, and integration with other biological
databases promise to enhance its impact in the years to come, further accelerating
scientific discovery and innovation.
