Protein Data Bank

Assalamualaikum,
today we learn about Protein Data Bank (PDB) using RasWin software. It's quite complicated, but interesting. We can observe the structure of protein in 3D with different kind of display such as wireframe, backbone, ball&stick and etc. We can also customize the colour according to temperature, structure, shapely and etc.

PDB was founded in 1971 by Brookhaven National Laboratory, New York. The first set of data were entered on punched cards. Then with magnetic tapes.After that it is  transferred to the Research Collaboratory for Structural Bioinformatics (RCSB) in 1998.Currently it holds 29,000 released structures.

The Protein Data Bank (PDB) is a repository for the 3-D structural data of large biological molecules, such as protein and nucleic acids.The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists  from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, and RCSB). The PDB is a key resource in areas of structural biology, such as structural genomic.
