A Prion is a normal protein that is found on the membranes of cells. The normal Prion protein (PrPC) consist mainly alpha helix rich 30-35kDa glycoprotein with 209 amino acid sequence and one disulfide bond (1). The disease causing form of normal prion protein named after scrapie (PrPSc) occurs when properly folded normal prion protein change its conformation. Although the exact tertiary structure of PrPSc still remains elusive but the previous studies have shown that the secondary structure of
