PDB- Protein Data Bank

wHAT IS pdb??

PDB stand for protein database. It is a repository for the 3-D structural data of large biological molecules, such as proteins and nucleic acids.The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists from around the world, can be accessed at no charge on the internet. The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.The PDB is a key resource in areas of structural biology, such as structural genomics.

We are also being told the website about the PDB which is http://www.rcsb.org/pdb/home/home.do

The website is the PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies. It is a resource for studying biological macromolecules.

In the class we have been taught to use the raswin / the rasmol  software to viewing and editing the structure molecules. we use trypsin molecules that we downloads in the website that i refer at the above. Using Rasmol, we can display the selected molecule as wireframe, backbone, sticks, spacefill, ribbons, strands, cartoons, or molecular surface. We also can change the colour of the molecule to monochrome, CPK, shapely, group, temperature, structure, user, model or alt. Besides, we also can rotate the molecule to view each sides.We are assigned to use 2 types of trypsin molecules.

This are the two type of trypsin molecules
