An enzyme-responsive artificial chaperone system which employs an amphiphilic amylose primer (dodecyl maltopentaose, C12-MP) as a surfactant and phosphorylase b was designed to enable protein refolding. Effective refolding of carbonic anhydrase B after both heat denaturation (70 degrees C for 10 min) and guanidine hydrochloride (6 M) denaturation was observed by controlled association between the protein molecules and the C12-MP primer micelle through an enzymatic reaction.
