What ATP binding does to the Ca(2+) pump and how nonproductive phosphoryl transfer is prevented in the absence of Ca(2+)

Under physiological conditions, most Ca(2+)-ATPase (SERCA) molecules bind ATP before binding the Ca(2+) transported. SERCA has a high affinity for ATP even in the absence of Ca(2+), and ATP accelerates Ca(2+) binding at pH values lower than 7, where SERCA is in the E2 state with low-affinity Ca(2+)-...
