LITERATURE
42 - 80
the first unfolding transition at 42°C leads to a loss of 15-20% of the secondary structure content of the protein and 80% loss in activity. The second unfolding transition at 80°C represents unfolding of the bulk of the protein
50
-
5 min, up to 98% loss of activity. A combination of Gln, MgCl2, and KCl protects against thermal inactivation
