title: Involvement of polyphosphoinositides in the ATP turnover of intact human erythrocytes and in the ATPase activity of purified membranes.
abstract: The phosphorylation cycle of polyphosphoinositides is an important process among the ATP-consuming reactions of human erythrocytes with "low" ATP-affinity. It serves to maintain a high level of PI-4,5-P2 in the membrane.
