Expression

EC Number Organism Comment Expression
7.1.2.1 Zea mays an increased Na+/K+ ratio decreases the enzyme activity. A significant decrease in hydrolytic activity is observed at 25 mM Na+ concentration at pH 7.0 (reduction in active H+ flux is 20%). The active H+ flux is decreased to 80% when 100 mM K+ are substituted by 100 mM Na+ down
7.1.2.1 Beta vulgaris the active H+ flux is decreased to 60% when 100 mM K+ are substituted by 100 mM Na+ down
7.1.2.1 Beta vulgaris at 25 mM Na+ concentration, hydrolytic activity is not affected (reduction in active H+ flux is 5%) additional information
