Protein Data Bank

What is Protein Data Bank?
  • A repository for 3-D biological macromolecular structure.
  • It is obtained by using crystallography or NMR spectroscopy.
  • Founded in 1971 by Brookhaven National Laboratory, New York
    -PDB is an important resource for research in the academic, pharmaceutical, and biotechnology sectors

  • Format is save in mmCIF(macromolecular Crystallograhic Information File)
  • The dictionary definition language (DDL)  is structured in a way that data files that conform to this syntax can be readily loaded into a database

Software tools...

  • pdb-extract
  • ADIT
  • PDB Validation Suite


Data Query....


Compound InformationMyoglobin,Lysozyme
Number of chains1-5
Secondary structure contentPresent of alpha min 80%
  • Example of protein data bank content.


NAME EXPLANATION
Structure of ClpP in complex with ADEP1
Clp-family proteins are prototypes for studying the mechanism of ATP-dependent proteases because the proteolytic activity of the ClpP core is tightly regulated by activating Clp-ATPases. The structures of Bacillus subtilis ClpP alone and in complex with ADEP1 and ADEP2.
 
NAME EXPLANATION
TRYPSIN INHIBITOR (T1) FROM NICOTIANA ALATA
The three-dimensional structures of a series of 6-kDa trypsin inhibitors isolated from the stigma of the ornamental tobacco Nicotiana alata have been determined by 1H NMR spectroscopy combined with simulated annealing calculations
