LITERATURE
dithioerythritol stabilizes during purification
-
freeze-thawing inactivates purified enzyme
freezing of dilute enzyme solution inactivates, concentration procedures lead to considerable loss of activity
-
glycerol 20% stabilizes
-
PMSF, EDTA and 2-mercaptoethanol stabilize during purification
-
purified enzyme has tendency to undergo transition to a lower specific activity form
-
SH-reagents stabilize
-
stable to freezing and thawing, purified and crude
-
sulfhydryl reagents restore activity of partially denatured enzyme and protect against inactivation
-
UDP-glucose stabilizes during gel filtration
