[Thermoregulation of catalytic activity of enzymes polymeric derivatives].
Trypsin was immobilized on polymeric carriers with low critical solution temperature (LCST). Homopolymer of N,N-diethylacrylamide (DEAA), random copolymers of DEAA and acrylamide (AA), and block copolymers polyDEAA-polyAA were used as the carriers. It was shown that at a temperature above LCST all carriers have a conformation change and trypsin's polymeric derivatives precipitate. The maximal activity after phase transition keeps trypsin, immobilized on polyDEAA block in polyDEAA-polyAA block-copolymer.
