Аннотация:The kinetics of refolding of bovine carbonic anhydrase B was studied by a variety of methods over a wide range of times (from milliseconds to hours). It has been shown that protein refolding proceeds through three stages. At the first stage (t1/2 approximately equal to 0.03 s) hydrophobic clusters and a compact state of the chain are formed. At the second stage (t1/2 approximately equal to 140 s) hydrophobic clusters are desolvated and the rigid native-like hydrophobic core is formed. At the third stage (t1/2 approximately equal to 600 s) the native active protein is formed.
