摘要
We studied substrate specificity of Na+,Cl–(HCO3–)-ATPase. In most cases, replacement of ATP for other phosphate-containing substances resulted in not only pronounced suppression of phosphohydrolase reactions, but also dramatic changes of their responsiveness to the stimulating effect of monovalent ions. The data showed that Na+,Cl–(HCO3–)-ATPase is a highly specific enzyme for ATP.
