[Properties of anion-sensitive erythrocyte ATPase].

Properties of membrane-bound and soluble bicarbonate-dependent ATPase from rat erythrocytes were studied. In presence of Mg2+ and Mn2+ bicarbonate activated ATPase in membranes, Zn2+, Ba2+, Ni2+, Ca2+ and Co2+ were ineffective. Ca2+ did not stimulate also the soluble HCO3-- - ATPase. Dicyclohexyl carbodiimide inhibited the membrane-bound ATPase and did not affect the soluble enzyme.
