Inhibitors

EC Number Inhibitors Comment Organism Structure
7.2.2.13 Ca2+ CaCl2 up to 300 microM does not affect Na+/K+-ATPase activity, but CaCl2 above 1 mM inhibits the activity Bombyx mori
7.2.2.13 Ouabain ouabain up to 1 mM decreases silkworm ATPase activity to 42% of the maximal ATPase activity in presence of 10 mM NaCl and 30 mM KCl Bombyx mori
