acetyl-CoA and sodium pyruvate protects against cold inactivation. L-Asp decreases inactivation, 1 M sucrose gives complete protection
-
acetyl-CoA stabilizes quarternary structure of the enzyme
dilution results in irreversible inactivation, which can be partially avoided by addition of acetyl-CoA. Glycerol stabilizes
-
does not participate directly in the reaction mechanism, but may play a structural role essential to the integrity of the enzymes tetrameric structure
-
inactivated reversibly and converted to protomers by incubation at 0°C in the presence of high concentrations of Cl- salts of monovalent cations. MgCl2 or sucrose prevent inactivation
-
the presence of KCl at 10, 20, 50, and 100 mM potassium phosphate buffer-KCl buffer at 0°C leads to 85%, 44%, 17% and 0% loss of activity
-
upon dilution, there is dissociation of the catalytically active tetrameric enzyme species into inactive dimers. Reactivation of the enzyme results in reassociation of enzymic dimers into tetramers.
