GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
DTT and glycerol stabilize
-
DTT stabilizes
-
freezing and thawing inactivates
inactivation in air-saturated aqueous solution by X-irradiation, inactivation is mainly due to the action of OH radicals, to a minor extent to O2 radicals and H2O2
-
limited proteolysis with trypsin results in cleavage of malate synthase into two framents of respectively 45000 Da and 19000 Da
-
Mg2+ stabilizes
salt does not stabilize
-
trypsin, treatment for 10 min, about 50% loss of activity of enzyme form MSH, 92% loss of activity of enzyme form MSL
