25 | 80 | The activity of the CPS.A-CPS.B complex remains unchanged between 25-60 °C and then increases 54% at 70°C. The loss of catalytic activity above 80°C is indicated of thermal denaturation. The large increase in thermal stability at temperatures prior to thermal denaturation is not observed in the CPS.A-CPS.B-glutaminase-subunit complex. | Aquifex aeolicus |
