Enzyme-responsive artificial chaperone system with amphiphilic amylose primer

Area of Science:

• Biochemistry
• Protein Folding
• Biotechnology

Background:

• Protein misfolding is a significant challenge in biotechnology and medicine.
• Artificial chaperones offer a promising strategy for protein refolding.
• Enzyme-responsive systems provide controlled activation for biomolecular processes.

Purpose of the Study:

• To design and evaluate an enzyme-responsive artificial chaperone system for protein refolding.
• To investigate the efficacy of a dodecyl maltopentaose (C12-MP) primer and phosphorylase b in protein refolding.
• To demonstrate controlled protein refolding after denaturation using enzymatic triggers.

Main Methods:

• Development of an artificial chaperone system utilizing an amphiphilic amylose primer (dodecyl maltopentaose, C12-MP) as a surfactant.
• Incorporation of phosphorylase b as a key enzymatic component for controlled activation.
• Application of the system to refold carbonic anhydrase B after heat (70°C for 10 min) and guanidine hydrochloride (6M) denaturation.

Main Results:

• The enzyme-responsive system demonstrated effective refolding of carbonic anhydrase B.
• Controlled association between protein molecules and C12-MP primer micelles was achieved through enzymatic reaction.
• Successful refolding was observed for proteins subjected to both thermal and chemical denaturation.

Conclusions:

• The developed enzyme-responsive artificial chaperone system is effective for protein refolding.
• Enzymatic control over protein-chaperone interaction enables efficient refolding of denatured proteins.
• This system holds potential for applications in protein therapeutics and biotechnology.
