2.6.1.13 2-mercaptoethanol or DTT stabilizes 637120 2.6.1.13 activity of the purified enzyme is preserved by addition of pyridoxal 5'-phosphate 637098 2.6.1.13 pyridoxal 5'-phosphate is required during solubilization and purification 637107 2.6.1.13 pyridoxal 5'-phosphate slightly increases heat stability 637105 2.6.1.13 pyridoxal 5'-phosphate stabilizes 637098 2.6.1.13 stability enhanced by presence of DTT and glycerol 637108 2.6.1.13 unlike holo-hOAT, apo-hOAT is prone to unfolding and aggregation under physiological conditions. Under physiological conditions the apo-tetramer is slightly less prone to unfolding and aggregation than the apo-dimer 760090
