a Overview of the side- and tilted-view of the electron density map of the complete OMCC with the asymmetric unit highlighted with the colour of the respective individual proteins. b Top view of the electron density map of the full OMCC highlighting the outer-ring (left) and inner-ring (right) symmetries and their respective asymmetric unit protein densities. c Electron density of the OMCCIR (top) and OMCCOR (bottom) with the asymmetric unit docked into their respective density. The top right shows the refined TraVNTD (purple) model in its density and the bottom right shows the refined TraK1NTD (green) model in its density.
