Activating Compound

Activating Compound Comment Organism Structure
NaHCO3 stimulator of Mg2+-ATPase activity of CF1. The rate of ATP hydrolysis increases significantly, when 1 mM NaHCO3 is added to the medium (pH 7.8) Spinacia oleracea

Inhibitors

Inhibitors Comment Organism Structure

Temperature Range [°C]

Temperature Minimum [°C] Temperature Maximum [°C] Comment Organism
26 37 the rate of ATP hydrolysis depends on temperature. Ca2+-ATPase activity is stimulated with bicarbonate both at 26°C and at 37°C. Mg2+-ATPase activity is stimulated with bicarbonate at 37°C Spinacia oleracea
