Noncovalent Enzyme Nanogels via a Photocleavable Linkage.

ABSTRACT: Enzyme nanogels (ENGs) offer a convenient method to protect therapeutic proteins from in vivo stressors. Current methodologies to prepare ENGs rely on either covalent modification of surface residues or the noncovalent assembly of monomers at the protein surface. In this study, we report a new method for the preparation of noncovalent ENGs that utilizes a heterobifunctional, photocleavable monomer as a hybrid approach. Initial covalent modification with this monomer established a polymerizable handle at the protein surface, followed by radical polymerization with poly(ethylene glycol) methacrylate monomer and ethylene glycol dimethacrylate crosslinker in solution. Final photoirradiation cleaved the linkage between the polymer and protein to afford the noncovalent ENGs. The enzyme phenylala
