Inhibitors

Inhibitors Comment Organism Structure
Ca2+ CaCl2 up to 300 microM does not affect Na+/K+-ATPase activity, but CaCl2 above 1 mM inhibits the activity Bombyx mori
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

Metals/Ions

Metals/Ions Comment Organism Structure
K+ the KCl concentration giving the half-maximal activity i 1.2 mM. The Na+:K+ ratios giving the maximal activity are 1:3 to 3:1 Bombyx mori
Mg2+ the optimal concentration of MgCl2 is 3 mM in presence of 10 mM NaCl and 30 mM KCl Bombyx mori
additional information CaCl2 up to 300 microM does not affect Na+/K+-ATPase activity, but CaCl2 above 1 mM inhibits the activity Bombyx mori
Na+ the NaCl concentration giving the halfmaximal activity is 6.0 mM. The Na+:K+ ratios giving the maximal activity are 1:3 to 3:1 Bombyx mori
