we have identified a conserved motif in the LOC118487 protein that we have called the CHCH motif. Alignment of this protein with related members showed the presence of three subgroups of proteins, which are called the S (Small), N (N-terminal extended) and C (C-terminal extended) subgroups. All three sub-groups of proteins have in common that they contain a predicted conserved [coiled coil 1]-[helix 1]-[coiled coil 2]-[helix 2] domain (CHCH domain). Within each helix of the CHCH domain, there are two cysteines present in a C-X9-C motif. The N-group contains an additional double helix domain, and each helix contains the C-X9-C motif. This family contains a number of characterized proteins: Cox19 protein - a nuclear gene of Saccharomyces cerevisiae, codes for an 11-kDa protein (Cox19p) required for expression of cytochrome oxidase. Because cox19 mutants are able to synthesise the mitochondrial and nuclear gene products of cytochrome oxidase, Cox19p probably functions post-translationally during assembly of the enzyme. Cox19p is present in the cytoplasm and mitochondria, where it exists as a soluble intermembrane protein. This dual location is similar to what was previously reported for Cox17p, a low molecular weight copper protein thought to be required for maturation of the CuA centre of subunit 2 of cytochrome oxidase. Cox19p have four conserved potential metal ligands, these are three cysteines and one histidine. Mrp10 - belongs to the class of yeast mitochondrial ribosomal proteins that are essential for translation. Eukaryotic NADH-ubiquinone oxidoreductase 19 kDa (NDUFA8) subunit. The CHCH domain was previously called DUF657. Length = 35

Cytochrome c oxidase (CcO), the terminal oxidase in the respiratory chains of eukaryotes and most bacteria, is a multi-chain transmembrane protein located in the inner membrane of mitochondria and the cell membrane of prokaryotes. It catalyzes the reduction of O2 and simultaneously pumps protons across the membrane. The number of subunits varies from three to five in bacteria and up to 13 in mammalian mitochondria. Subunits I, II, and III of mammalian CcO are encoded within the mitochondrial genome and the remaining 10 subunits are encoded within the nuclear genome. Found only in eukaryotes, subunit VIb is one of three mammalian subunits that lacks a transmembrane region. It is located on the cytosolic side of the membrane and helps form the dimer interface with the corresponding subunit on the other monomer complex.

9.3.1 from EC) is an oligomeric enzymatic complex that is a component of the respiratory chain complex and is involved in the transfer of electrons from cytochrome c to oxygen []. In eukaryotes this enzyme complex is located in the mitochondrial inner membrane; in aerobic prokaryotes it is found in the plasma membrane. In eukaryotes, in addition to the three large subunits, I, II and III, that form the catalytic centre of the enzyme complex, there are a variable number of small polypeptide subunits. One of these subunits is the potentially haem-binding subunit, VIb, which is encoded in the nucleus []. ; GO: 0004129 cytochrome-c oxidase activity, 0005739 mitochondrion; PDB: 1OCC_U 1OCR_U 2DYS_H 3ASO_H 3AG3_U 2EIL_H 2EIJ_U 3AG2_U 3ABM_U 2EIN_U ....
