Effects of p-nitrophenylphosphate on Ca2+ transport in inside-out vesicles from human red-cell membranes.
Ca2+-ATPase activity and Ca2+ uptake in inside-out vesicles from human red cell membranes are changed in parallel by p-nitrophenylphosphate. This indicates that, unlike the Ca2+ pump of sarcoplasmic reticulum, the Ca2+ pump of the red cell membrane does not utilize p-nitrophenylphosphate hydrolysis to drive Ca2+ transport.
