WHAT IS PROTEIN DATA BANK?

The Protein Data Bank (PDB) is a repository for the three-dimensional structural data of large biological molecules.The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologist and biochemist from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, and RCSB).

The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB. The PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies.

There are 5 proteins that we are able to find out and each of these proteins has many examples (only one shown):

• HtrA: Serine protease HTRA1
• Subtilisin: SUBTILISIN BPN'
• Collagenase
• Aminopeptidase
• Carboxypeptidase
