title: Net ATP synthesis by running the red cell calcium pump backwards.
abstract: Ca2+ loaded inside-out vesicles from human red blood cells, yielding C2+ into a Ca2+ free medium with 4 mM EGTA, 2 mM ADP and 10 mM phosphate, produced an excess of 14.9 pmoles . min-1 . (mg protein)-1 of ATP compared to controls in which the transmembrane Ca2+ gradient was abolished by the ionophore A 23 187.
