-Complex III of the electron transport chain contains as many as 11 subunits per monomer.  In this opening structure it is shown with 9. (The 'initial scene' green link available in the Jmol applet shows the dimer structure along with Heavy Chain (Vh) Of Fv-Fragment, Light Chain (Vl) Of Fv-Fragment and Cytochrome C, Iso-1 all of which are a part of 1KYO.PDB.) <scene name='Complex_III_of_Electron_Transport_Chain/Labels_applied/1'>Show orientation</scene> of the complex within the inner mitochondrial membrane with labels. <scene name='Complex_III_of_Electron_Transport_Chain/View_one_subunit/1'>Coloring one subunit grey</scene> reveals that one of the peptides of each subunit invades the space of the other subunit. <scene name='Sandbox61/View_3_active_subunits/1'>Three of the subunits</scene> of each monomeric unit have a direct role in the passage of electrons in the respiratory chain. The subunits that are colored are active in the electron transport chain. The interior spaces which are created by the positions of the other subunits have a role in the movement of the substrates from one active site to another, and these peptides have other catalytic activities.
