Experiment 2: Retrieving sequence from Protein Data Bank
, INTRODUCTION
The world-wide Protein Data Bank, which was founded by the late Walter Hamilton at
Brookhaven National Laboratories in 1971, is now the most important database for biological
macromolecular structures. The Protein Data Bank (PDB) is a structure database that stores,
annotates, and distributes sets of atomic coordinates as well as protein, nucleic acid, and
carbohydrate structures.
The home pages of the Protein Data Bank contains links to the data files themselves, to
expository and tutorial material including short news items and the RCSB PDB
Newsletter, to facilities for deposition of new entries, and to specialized search software
for retrieving structures. The Box shows part of the PDB entry for a specific structure.
The information contained includes:
What protein is the subject of the entry, and what species it came from
Who solved the structure, and literature references
Experimental details about the structure determination, including information
related to the general quality of the result, such as the resolution of an X-ray
structure determination, and stereochemical statistics
The amino acid sequence
The atomic coordinates
What additional molecules appear in the structure, potentially including
cofactors, inhibitors and water molecules
Assignments of secondary structures: helices, sheets
Disulphate bridges
Proteins are not in a straight line, despite the fact that they are made up of amino acid
strings. The strands form certain forms by twisting, bending, and folding. The shape of a
protein must be studied using PDB in order to determine the specific functions of each
protein. Antibodies, for example, are shaped like a Y. This allows these immune-system
proteins to bind to foreign molecules like bacteria or viruses while also recruiting other
immune-system proteins on the other end. The donut-shaped DNA polymerase III. As it
copies its genetic information, this helps it construct a ring around DNA. Enzymes, for
example, have grooves and pockets that help them hold on to other molecules in order to
speed up chemical reactions. Proteins that are misfolded, or misshapen, can cause illnesses.
They frequently fail to function properly and can accumulate in tissues. Misfolded proteins
cause diseases such as Alzheimer's disease, Parkinson's disease, and cystic fibrosis. We used
