Anisotropy of CuL in presence of Pic2, Mrs3 and mitochondrial membranes. (a) Fluorescence anisotropy (FA) of CuL (Ex320 Em400) with addition of reconstituted Pic2 or Mrs3 in proteoliposomes prepared from extracted egg-yolk lipids. Control FA of equal quantity of lipids without protein added was subtracted from each point. (b) FA of CuL with mitochondrial membranes prepared by sonication of intact mitochondria followed by centrifugation from pic2Δ yeast expressing empty vector (VEC), PIC2 or MRS3. Protein concentrations were determined by Bradford assay, and curves are fit with a hyperbola function.
