Turnover (kp (s⁻¹)) for PMCA in the presence of different phospholipid molar fractions

kp is the ratio between the Ca²⁺-ATPase activity from Fig. 1A and the Ep values obtained in Fig. 5 in the presence of the X_PC shown in the table.

XPC	kp
	s−1
XDLPC = 0.40	404 ± 34
XDLPC = 0.70	403 ± 17
XDMPC = 0.25	474 ± 11
XDMPC = 0.70	233 ± 21
XDOPC = 0.30	274 ± 19
