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 characterised 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 [2]. Eukaryotic NADH-ubiquinone oxidoreductase 19 kDa (NDUFA8) subunit [3]. The CHCH domain was previously called DUF657 [4].	Domain
