at physiological temperatures the mutant enzymes looses only 10% of their activity after 20 min in the presence of 0.01 mM NADP+ |

mutant enzymes are more thermostable than the wild-type enzyme |

activity is increased 2-3fold by heating at 25°C (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 0°C but is not reversed at temperatures between 20°C and 30°C |

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

pH 7.2, 24 h: wild-type enzyme loses 42% of its initial activity, mutant enzyme G163S loses 73% of its initial activity, mutant enzyme G163D loses 94% of its initial activity. Stability of all three enzymes is enhanced by addition of NADP+ |

the stripped enzyme, much less stable than holoenzyme, inactivates irreversibly within 2 d |

60 min, the wild-type enzyme is completely stable, the mutant P409R shows 86% reduced thermal stability compared to the wild-type enzyme |
