LITERATURE
2-mercaptoethanol enhances stabilization provided by ATP. ATP stabilizes against heat inactivation
-
50% glycerol stabilizes for several days at 4°C
-
K+ and phosphate stabilize
MgATP2-, ATP or sulfhydryl compounds increase the lability of the enzyme
-
PMSF, benzamidine, and 20% v/v glycerol stabilize
-
stability decreases markedly with further purification
-
stabilized by glycerol or by ATP
-
the enzyme precipitates after a week at concentrations as low as 0.1 mg/ml
-
