LITERATURE
0 - 30
-
activity is increased 2-3fold by heating at 25C (either at pH 10 in 0.5 M glycine KOH buffer or at pH 5 in 0.05 M sodium citrate buffer) prior to assay, the stimulation is reversed by chilling to 0C but is not reversed at temperatures between 20C and 30C

-
inactivation at 4C is partially reversed at room temperature, especially with added NADP+
