摘要: Enzymatically synthesized glycogen (ESG) bearing hydrophobic groups were prepared to construct a new artificial molecular chaperone system. The radius of the amphiphilic ESG nanogel was approximately 15 nm. nanogels prevented irreversible aggregation carbonic anhydrase. Cyclodextrin induced release anhydrase in its active form via one-step mechanism without dissociation nanogels.
