Description : (at2g30920 : 196.0) The enzyme encoded by this gene has been shown to complement the Saccharomyces cerevisiae coq3 mutation and, therefore, to have hexaprenyldihydroxybenzoate methyltransferase activity. It is however likely that, in Arabidopsis, the enzyme catalyzes the methylation of nonaprenyldihydroxybenzoate as it is the prevalent polyprenoid in this plant species. The enzyme is a mitochondrial-localized methyltransferase involved in ubiquinone biosynthesis.; coenzyme Q 3 (COQ3); CONTAINS InterPro DOMAIN/s: Methyltransferase type 11 (InterPro:IPR013216), Ubiquinone biosynthesis O-methyltransferase (InterPro:IPR010233); Has 7105 Blast hits to 7105 proteins in 1734 species: Archae - 120; Bacteria - 4165; Metazoa - 130; Fungi - 181; Plants - 86; Viruses - 0; Other Eukaryotes - 2423 (source: NCBI BLink). & (reliability: 392.0) & (original description: no original description)
