3.5.5.5	15	55	exposure of the enzyme at 15, 25, and 35°C for 5 h causes 8%, 15%, and 28% decrease in arylacetonitrilase activity, respectively. A further increase in the temperature to 45 and 55°C results in 58% and 90% decrease in activity, respectively. The half-life of this enzyme at 15, 25, 35, 45, 50, and 55°C is 31 h, 16 h, 9 h, 4 h 30 min, 3 h 20 min, and 2 h 40 min, respectively	733546
