Protein Data Bank

This the 4th post for KOS course,
This is the other new thing that I have learned during my computer class...
We learn bout how to create a unique and colorful protein using RasMol. RasMol is a program for molecular graphics visualisation. You can download it from this website.
I tell you it was a 'bit" interesting even I am taking mathematics..hahaha! :)

Here are some information about protein data bank.

  •  A repository for 3-D biological macromolecular structure 
  • All data are available to the public 
  • It includes proteins, nucleic acids and viruses 
  • Obtained by X-Ray crystallography (80%) or NMR spectroscopy (16%) 
  • Submitted by biologists and biochemists from around the world  
  •  
You can go to Portal of Biological Macromolecular Structures to look out for more molecular structures.
I show you the protein picture of Crystal structure of a LexA protein from Thermotoga maritima that I created using RasMol sofware..have a look! (^_^)



You can also rotate, change the colour and change other settings of molecule structure. Here are the picures :
