摘要：
To study the intrinsic structural properties of three human prion helices and analyse their stability, we conducted molecular dynamics simulations, applied helix propensity predictions and evaluated the energetic contribution of the helical regions to the PrP protein stability. Our results suggest that three helices present different stability and the helix 2 results the least stable.
