COMMENTARY hide
LITERATURE
30 - 40
-
the enzyme is relatively stable below 30°C, but the original bands become faint and the bands of aggregated enzyme (above 70 kDa) appear when the temperature is above 40°C
30 - 44
stable at, crayfish arginine kinase easily forms aggregates at temperatures above 44°C
35
-
10 min, stable
45 - 65
46 - 60
-
the activity of wild type enzyme changes a little after heat treatment for 10 min at temperatures below 45°C. A steep decrease of activity is observed after 10 min between 45 and 60°C, and a complete loss of activity occurs above 65°C. The midpoint of thermal inactivation of wild type enzyme is at about 52°C
5 - 50
-
purified enzyme, activity is relatively stable from 5°C to 23°C, but decreases rapidly from 25°C to 40°C. The activity is almost abolished at 50°C, half -life at 31.88°C
55
-
10 min, complete loss of activity
