Caption: The FoF1 synthase is oriented so that the F1 component attached via histidine linkages to a nickel-coated microscope slide (gray rectangle). A gold nanorod is bound by avidin-biotin to the c-subunit ring of the Fo complex (represented by light and dark gray bands), which rotate relative to subunit-a (bright green dowels). An axel (dark green) connects the FoF1 motors. The stabilizing nanodisc is portrayed with blue segments and brown lipid bilayer dumbells.
