-
30°C: maximal activity, 40°C: 21% of maximal activity
30 - 50
a gradual loss in the enzyme's activity is recorded with the increase of temperature from 30 to 90°C. The enzyme exhibits 60% of its activity at 50°C, whereas, the activity is completely lost at temperature 70°C and above
30 - 55
more than 70% activity between 30 and 55°C
30 - 65
