In fa,ct conformational change is a biological action for protein to perform an action which is important for living organism. The reasons are some environmental impulses to cause these conformational changes. Protein or any large biological molecule subjected to conformational change are flooring in biological liquid with minimum friction. Therefore, small impulses cause movement of folding in proteins. Changing of pH, bonding of cations or anions to the proteins or electrical polarity may cause these conformational changes.
