Abstract
We studied the effects of bivalent metal ions on activity of Na+Cl–HCO3 –ATPase was studied In contrast to Ba2+ Co2+ Zn2+ and Mn2+ ions Ca2+ and Mg2+ ions in a concentration of 025 mM completely inhibited this enzyme Histamine in vivo significantly decreased the inhibiting effect of Ca2+ on Na+Cl–HCO3 –ATPase A possible mechanism of regulation of enzyme activity by Ca2+ ions and its possible relation with CFTR protein providing permeability of enterocyte apical membrane for Cl– ions was proposed
