Demethoxyubiquinone hydroxylase, ferritin-like diiron-binding domain; Demethoxyubiquinone hydroxylases (DMQH) are members of the ferritin-like, diiron-carboxylate family which are present in eukaryotes (the CLK-1/CAT5 family) and prokaryotes (the Coq7 family). DMQH participates in one of the last steps of ubiquinone biosysnthesis and is responsible for DMQ hydroxylation, resulting in the formation of hydroxyubiquinone, a precursor of ubiquinone. CLK-1 is a mitochondrial inner membrane protein and Coq7 is a proposed interfacial integral membrane protein. Mutations in the Caenorhabditis elegans gene clk-1 affect biological timing and extend longevity. The conserved residues of a diiron center are present in this domain.

13-150 1.13e-08

Ferritin-like superfamily of diiron-containing four-helix-bundle proteins; Ferritin-like, diiron-carboxylate proteins participate in a range of functions including iron regulation, mono-oxygenation, and reactive radical production. These proteins are characterized by the fact that they catalyze dioxygen-dependent oxidation-hydroxylation reactions within diiron centers; one exception is manganese catalase, which catalyzes peroxide-dependent oxidation-reduction within a dimanganese center. Diiron-carboxylate proteins are further characterized by the presence of duplicate metal ligands, glutamates and histidines (ExxH) and two additional glutamates within a four-helix bundle. Outside of these conserved residues there is little obvious homology. Members include bacterioferritin, ferritin, rubrerythrin, aromatic and alkene monooxygenase hydroxylases (AAMH), ribonucleotide reductase R2 (RNRR2), acyl-ACP-desaturases (Acyl_ACP_Desat), manganese (Mn) catalases, demethoxyubiquinone hydroxylases (DMQH), DNA protecting proteins (DPS), and ubiquinol oxidases (AOX), and the aerobic cyclase system, Fe-containing subunit (ACSF).
