Here, we applied cryo-electron microscopy to determine the structures of FF ATP synthase and respiratory supercomplexes (SCs) on sub-mitochondrial particles (SMPs) isolated from bovine heart mitochondria. Most FF complexes were observed as dimers stabilized by the regulatory factor IF₁, and a tetrameric assembly comprising two FF-IF₁ dimers arranged linearly was also identified. This finding indicates that the tetrameric units of FF are present in the mitochondrial inner membrane and contribute to shaping cristae tips in mammalian mitochondria. F domain maps resolve the e-subunit- c₈-ring interface and show no discrete density for a tightly bound lipid within the c₈-ring. In addition to the previously reported SCs compositions CI₁CIII₂CIV₁ and CI₁CIII₂CIV₂, our analysis identified an additional assembly with the composition CI₁CIII₂CIV₃, as well as a CI₂CIII₂CIV₆ mega-complex. This approach enables rapid structural determination of FF ATP synthase and SCs from minimal membrane fractions, providing a foundation for elucidating the molecular basis of metabolic disorders and mitochondrial diseases at the level of higher-order architecture.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
