Figure 7.
The inhibitory effect of CAX1-NRR peptide concentration on ΔpH-dependent 10 μm Ca2+ transport by sCAX1 (black circle) or sVCAX1 (black square) into yeast endomembrane vesicles at a 10-min time point. The inhibitory effect of a control peptide of similar size and charge to CAX1-NRR peptide on ΔpH-dependent 10 μm Ca2+ transport by sCAX1 is also shown (white circle). Results are displayed as a percentage of the Ca2+ uptake measured in the absence of peptide. Results are the mean (±se) of two independent experiments.
