1.13.11.88 15 20 conversion after 12 h increases from 67.0 to 84.1% with the temperature increase from 15 to 20°C, and it decreases beyond 20°C 1.13.11.88 20 - stable for 30 min 1.13.11.88 20 40 at 20°C and 30°C, more than 90% of initial activity residue is detected after 150 min incubation. However, its activity is decreased when incubated at temperatures higher than 40°C, about 50% of its initial activity is detected at 40°C after 30 min of incubation and almost inactivated at 50°C 1.13.11.88 25 35 the wild type enzyme shows 53.2% residual activity after 15 min at 35°C. The enzyme has half-lives of 967.2, 49.8 and 7.8 min at 25, 30, and 35°C, respectively 1.13.11.88 30 - 30 min, 7% loss of activity 1.13.11.88 50 - 30 min, complete loss of activity
