Supplementary Figure 5: Structural alignment of the two halves of the III2IV2 SC.
From: Structure of yeast cytochrome c oxidase in a supercomplex with cytochrome bc1

a,b, Side (a) and top (b) views of a structural alignment of the two halves of the III2IV2 SC, aligned on their core CIII subunits, Cor1, Cor2 and cytochrome b. This reveals minimal deviation of Cox5A at the SC interface (~0.3–0.5 Å), but a larger deviation of Cox13 (3.0 Å), at the extreme periphery of the SC. Cox26 and Qcr10 are displayed in green and red, respectively.
