The highly divergent ribosomes of human mitochondria (mitoribosomes) synthesize
13 essential proteins of oxidative phosphorylation complexes. We have determined
the structure of the intact mitoribosome to 3.5 angstrom resolution by means of
single-particle electron cryogenic microscopy. It reveals 80 extensively
interconnected proteins, 36 of which are specific to mitochondria, and three
ribosomal RNA molecules. The head domain of the small subunit, particularly the
messenger (mRNA) channel, is highly remodeled. Many intersubunit bridges are
specific to the mitoribosome, which adopts conformations involving ratcheting or
rolling of the small subunit that are distinct from those seen in bacteria or
eukaryotes. An intrinsic guanosine triphosphatase mediates a contact between the
head and central protuberance. The structure provides a reference for analysis of
mutations that cause severe pathologies and for future drug design.
