Protein denaturation plays a crucial role in cellular processes. In this study, denaturation of HIV-1 Protease (PR) was investigated by all-atom MD simulations in explicit solvent. The PR dimer and monomer were simulated separately in 9 M acetic acid (9 M AcOH) solution and water to study the denaturation process of PR in acetic acid environment. Direct visualization of the denaturation dynamic...

Recent theoretical predictions on DNA mechanical separation induced by pulling forces are numerically tested within a model in which self-avoidance for DNA strands is fully taken into account. DNA strands are described by interacting pairs of self avoiding walks (SAW) which are pulled apart by a force applied at the two extremities. The whole phase diagram is spanned by extensive Monte Carlo (M...

The change produced in native proteins by various agents which results in loss of their characteristic properties and changes in solubility is called denaturation. The term, however, may be applied to structural and physical changes in the protein molecule which differ widely with the particular agent used. Urea denaturation differs in many respects from both heat and radiation denaturation. Ur...

The denaturation of hemoglobin by salicylate in neutral solution is completely reversible. There is a mobile equilibrium between native and denatured hemoglobin in neutral salicylate solution. The higher the salicylate concentration the greater is the percentage denaturation. When there is a mobile equilibrium between the native and denatured forms of a protein, denaturation is caused by the ad...
