LITERATURE

2-mercaptoethanol or DTT stabilizes

Manduca sexta

-

637120

activity of the purified enzyme is preserved by addition of pyridoxal 5'-phosphate

Rattus norvegicus

-

637098

pyridoxal 5'-phosphate is required during solubilization and purification

Schistosoma mansoni

-

637107

pyridoxal 5'-phosphate slightly increases heat stability

Clavibacter michiganensis subsp. sepedonicus

-

637105

pyridoxal 5'-phosphate stabilizes

Rattus norvegicus

-

637098

stability enhanced by presence of DTT and glycerol

Cucurbita pepo

637108

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
