Figure 1

Structure of complex I with supernumerary subunits highlighted. Core subunits in the matrix arm are colored light blue. Core subunits in the membrane arm are colored beige. Supernumerary subunits that are described in this review are colored and labeled. Other supernumerary subunits are white. The two views are rotated 180° relative to each other. The structure is from the Protein Data Bank file 5xtd (PDB id = 5xtd) [9]. All structural images were generated using Jmol (http://www.jmol.org).
