Inhibition of ATPase Activity by Theaflavins

	Membrane-bound ATPase Activity^a		F₁-ATPase Activity^b
Inhibitor	IC₅₀	Maximum inhibition	IC₅₀	Maximum inhibition
Inhibitor	(μM)^c	(%)^c	(μM)^c	(%)^c
TF1	60	85	4.0	85
TF2A	20	95	3.0	90
TF2B	15	95	1.5	95
TF3	10	90	0.7	90
EGCG	30	95	4.5	90

Membrane-bound ATPase activity was about 0.7 μmoles ATP/min/mg protein

F₁-ATPase activity was about 1.8 μmoles ATP/min/mg

IC₅₀ concentrations and maximum inhibition % were determined from two replicates of 5-6 concentrations of inhibitor. The data are displayed in Supplementary Figure1.
