WebThe Anfinsen experiment: spontaneous folding The seminal experiment reported by Anfinsen demonstrated that RNase A could be fully denatured by: 1. reducing the disulfide bonds (using B-mercaptoethanol) 2. dissolving in 8 M urea and then fully renatured on diluting out the urea and allowing the disulfides to reoxidize. WebThe temperature-sensitive bacteriophage λ c 1857 repressor protein rapidly renatures after thermal inactivation. E. coli mutants in the heat shock protein genes dnaK, dnaJ , and grpE do not efficiently reactivate heat-denatured repressor. Our results suggest that protein refolding is promoted by heat shock proteins and that such a process is the basis of the … class 11 hindi grammar
