PDB & Rasmol

Today, we learned about Protein Data Bank, or in its short form, we call it as PDB. The Protein Data Bank is a repository for the 3-D structural data of large biological molecules, such as proteins and nucleic acis. Typically, the data are obtained by X-ray crystallography or NMR spectroscopy and submittted by biochemists and biologist from around the world. Besides, they are freely accessible on the Internet via the websites of its member organisations, for instance, PDBe, PDBj and RCSB. In addition, PDB is a key resource in areas of structural biology, such as structural genomics. For most major scientific journals, and some funding agencies, such as the NIH in the USA, now need scientists to submit their data to the PDB.

After learning about PDB, we are asked to do some assignment about this topic. In this assignment, we need to collect the information of the molecular gained from the website: http://www.pdb.org/pdb/home/home.do 

Apart from that, we have to edit some of the molecular, such as Collagenase, Subtilisin, Kexin and Signal Peptidase. Therefore, below is the information about each of them.
