2.7.1.3	25	-	25°C, 2 h, totally inactivated in 0.1 M KCl/50 mM Tris-HCl (pH 9.0). Stabilizing effect of KCl increases with increasing KCl concentration between 0.1 and 2.5 M (ranging from 30 to 98% of the total). Addition of 50 mM phosphate aids in stabilization of ketohexokinase activity in 0.1 M KCI for about 24 h. Although it is inhibitory for expression of ketohexokinase activity, (NH4)2SO4 stabilizes	727726
