metal ion-chelated polyethyleneimine-immobilized enzyme PEI-Mn2+-GDH exhibits a half-life that is enhanced by 5.6folds in aqueous phase at 85°C
additional information
thermal inactivation of GDH is not a simple first-order process, thermal deactivation kinetics, modelling, overview

the recombinant enzyme is initially more stable in the presence of DHA than in its absence, maintaining 100% activity over 120 min, but it quickly inactivates after 120 min, losing over 84% of its activity in the next 5 h

purified recombinant enzyme, pH 12.0, loss of about 25% activity after 100 min

recombinant enzyme, maintaining 65% activity after 2 h
metal ion-chelated polyethyleneimine-immobilized enzyme PEI-Mn2+-GDH exhibits greater heat resistance than free enzyme GDH. After incubation for 90 min at 70°C, PEI-Mn2+-GDH still presents nearly 50% of its initial activity, while free GDH is almost totally inactivated
