On the activation mechanism of the H+‐ATP synthase and unusual thermodynamic properties in the alkalophilic cyanobacterium Spirulina platensis

The activation requirements and thermodynamic characteristics of ATP synthase from the alkalophilic cyanobacterium Spirulina platensis were studied in coupled membrane vesicles. Activation by methanol increased the Vmax, while the Km for MgATP was unaffected (0.7 mM). We propose that in Sp. platensi...
