WebMay 25, 2007 · Equilibrium unfolding and refolding studies of a model superfamily member, Fas-associated death domain protein indicate that the process is cooperative, two-state and reversible. Stopped-flow fluorescence studies reveal that the folding is rapid and biphasic with the majority of the hydrophobic core forming in the first phase. WebFeb 26, 2010 · Some proteins, particularly those in harsh environments full of proteases, have evolved to virtually eliminate partial unfolding, significantly reducing their rate of …
