-
the enzyme is completely stable for 120 h in buffer with stirring at 25°C, and the activity even increases 30% if the enzyme solution is also aerated in a similar experiment
30 - 60
-
30 min, stable
40 - 60
the purified recombinant His-tagged enzyme shows half-lifes of 11.2 min, 5.3 min, and 2.7 min for incubation at 40°C, 50°C, and 60°C, respectively
65
-
10 min, about 40% loss of activity
additional information
the thermostability of GalOx from Fusarium oxysporum expressed in Escherichia coli is significantly lower than the thermostability of enzymes from other Fusarium strains
