Ubiquinone biosynthesis protein COQ9, mitochondrial

UniProtKB accession:  O75208

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Membrane-associated protein that warps the membrane surface to access and bind aromatic isoprenes with high specificity, including ubiquinone (CoQ) isoprene intermediates and presents them directly to COQ7, therefore facilitating the COQ7-mediated hydroxylase step (PubMed:25339443, PubMed:30661980, PubMed:38425362). Participates in the biosynthesis of coenzyme Q, also named ubiquinone, an essential lipid-soluble electron transporter for aerobic cellular respiration (PubMed:25339443, PubMed:30661980).
