Cytochromes c are widespread respiratory proteins characterized by the covalent
attachment of heme. The formation of c‐type cytochromes requires, in all but a few …

Eukaryotic cytochrome c oxidases are complex oligomeric membrane proteins composed of
subunit polypeptides encoded by both nuclear and mitochondrial genomes. While the …

As part of the respiratory chain, c-type cytochromes are essential electron transporters. They
are characterized by the covalent attachment of a heme prosthetic group. The biogenesis of …

The cbb3-type cytochrome c oxidases (cbb3-Cox) constitute the second most abundant
cytochrome c oxidase (Cox) group after the mitochondrial-like aa3-type Cox. They are …

Heme a is an essential metalloporphyrin cofactor of the mitochondrial respiratory enzyme
cytochrome c oxidase (CcO). Its synthesis from heme b requires several enzymes, including …

Cytochrome c (Cc) and cytochrome c peroxidase (CcP) form a physiological complex in the
inter-membrane space of yeast mitochondria, where CcP reduces hydrogen peroxide to …

Biogenesis of mitochondrial cytochrome c oxidase (COX) is a complex process involving the
coordinate expression and assembly of numerous subunits (SU) of dual genetic origin …

Cytochrome c oxidase is the terminal complex of the respiratory chains in the mitochondria
of nearly all eukaryotes. It catalyzes the reduction of molecular O 2 to water using electrons …

The assembly of cytochrome c oxidase (CcO) in yeast mitochondria is shown to be
dependent on a new assembly factor designated Coa1 that associates with the …

The known subunits of yeast mitochondrial cytochrome c oxidase are reviewed. The
structures of all eleven of its subunits are explored by building homology models based on …
