What is meant by PDB?
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids.
Why is PDB ID important?
PDB is a very important database when it comes to the areas of structural biology. Structures in PDB have wide applications. They can be used for various studies including identification of new protein structures via in silico approaches or can be used for protein–nucleic acid interaction studies.
How many structures are in the PDB?

How do I find PDB?
PDB files that have been viewed previously can be loaded using File/ Recent PDB Codes….To Search the PDB and Download a Structure:
- Click on the search tab and enter a search string or PDB code.
- A table containing the results will be displayed.
- Double click on a row to load the PDB file. Read more about PDB search here.
What is a PDB chain?
pdb: “chain A” and “chain B”. Each amino acid in a chain is called a residue, and they are numbered sequentially. Protein structures that are determined by NMR spectroscopy typically correspond to multiple structures in the PDB file. These structures are called models.
Who created PDB?
The PDB was established in 1971 at Brookhaven National Laboratory under the leadership of Walter Hamilton and originally contained 7 structures. After Hamilton’s untimely death, Tom Koetzle began to lead the PDB in 1973, and then Joel Sussman in 1994.
How do I search PDB?
You can use keyword searching or type in the PDB code you are interested in….To Search the PDB and Download a Structure:

Who funds the PDB?
Since 1995, the PDB, under the continuing supervision of Joel Sussman, has been funded by a cooperative agreement providing ~9 million US dollars over four years.
What is occupancy in PDB?
The occupancy value is used to indicate the fraction of molecules that have each of the conformations. Two (or more) atom records are included for each atom, with occupancies like 0.5 and 0.5, or 0.4 and 0.6, or other fractional occupancies that sum to a total of 1.
When was PDB founded?
1971
The PDB was established in 1971 at Brookhaven National Laboratory under the leadership of Walter Hamilton and originally contained 7 structures. After Hamilton’s untimely death, Tom Koetzle began to lead the PDB in 1973, and then Joel Sussman in 1994.
What is in a PDB file?
A program database file (extension . pdb) is a binary file that contains type and symbolic debugging information gathered over the course of compiling and linking the project. A PDB file is created when you compile a C/C++ program with /ZI or /Zi or a Visual Basic, Visual C#, or JScript program with the /debug option.
Who runs the Protein Data Bank?
RCSB PDB (RCSB.org) is the US data center for the global Protein Data Bank (PDB) archive of 3D structure data for large biological molecules (proteins, DNA, and RNA) essential for research and education in fundamental biology, health, energy, and biotechnology.
Who started PDB?
Where is the PDB code?
Every molecular model (atomic coordinate file) in the Protein Data Bank (PDB) has a unique accession or identification code. These codes are always 4 characters in length.
