The translocase of the outer mitochondrial membrane (TOM) is the main entry gate for proteins1-4 . Here we use cryo-electron microscopy to report the structure of the yeast TOM core complex5-9 at 3.8 Å resolution. The structure reveals the high-resolution architecture of the translocator consisting of two Tom40 β-barrel channels and α-helical transmembrane subunits, providing insight into critical features conserved in all eukaryotes1-3 . Each Tom40 β-barrel is surrounded by small Tom subunits, and tethered by two Tom22 and one phospholipid...
