As Justin pointed out, there is a vast literature on this topic, you need to ask yourself what you seek, and look at many review articles to find some reasonable starting points for you own needs and designs. Beyond that, it's a lot of hard work...

Thanks for your advice... Could you please refer me some papers regarding this ....

If you used a fragment approach you could potentially (read lots of papers on REMD) isolate nucleation sites, but minus the tertiary interaction scheme you could not tell a compelling story. Now, if you want to find nucleation sites and see if there are spatially proximal sites and simulate them together... You might begin to tell a story.

Thanks for your reply. I want to whether does it make any sense or is it possible to simulate fragments of proteins and find their folding rate and then correlate it to folding rate of whole protein ??

Simulating arbitrary parts of a protein may or may not produce any relevant information, likely the latter. Independently folding domains might be simulated in isolation, but if there is a chance that the peptide sequences have any effect on neighboring residues or even more distal sites, you'll never produce anything useful.

      Hi,
      I want to know whether it's possible to calculate the folding
      rate of 20 residue peptide folding into a beta-hairpin using

  Anything is possible ;)  But seriously, there is existing literature
  on such topics, I suspect you can find methodology that will suit
  your needs.
