a Three-dimensional segmented cryo-EM density map of the Fd-reduced Rnf complex coloured by subunits. b Overall structure of the Rnf complex shown in cartoon representation. c Graphical representation of the Rnf complex showing the topology of the membrane-bound area along with the cofactors harboured by each subunit. d Cofactor content in the Fd-reduced Rnf complex, with edge-to-edge distances between the FeS clusters and cofactors shown in ångströms. See Supplementary Fig. 6 for a comparison of all resolved cryo-EM structures.
