-
after 5 min complete activity loss
20 - 60
relatively stable from 20 to 60°C but activity drops dramatically at 70°C, AtraAOX2 preheated at 60°C, shows biphasic inactivation, with a rapid decrease from 0 to 10 min, and monotonous decrease thereafter, with an estimated half-life of 33 min
30 - 55
-
enzyme retains at least 80% of initial activity for 30 min
35
the activity remains almost unchanged after 24 h in the absence of organic solvents at 35°C, enzyme is relatively stable in the presence of methanol, 2-propanol and acetonitrile
55
at 55°C, the enzyme undergoes a conformational change producing an inactive form, conversion is reversible
60 - 70
-
relatively stable
