H176N

Geobacillus stearothermophilus

the mutant shows a Km value 5times smaller than for the wild type enzyme while the Km value for arsenate is about 5times larger. The mutant has a significantly reduced thermal stability at 65°C. The half-life for thermal denaturation for the mutant holoenzyme is increased nearly 100fold over the corresponding value for the apoenzyme
