-
immobilized actinidin is more stable than free form at pH 3 and pH 12 after 60 min incubation leading to 30% residual activity of immobilized form and complete inactivation of the free form

additional information
-
thermal stability of Act d 1 and Act d 2 is strongly pH dependent. Act d 1 is irreversibly destabilized in acidic solutions (pH 3.5)
