3,4-Dihydroxy-5-hexaprenylbenzoate methyltransferase (DHHB-MTase) is the product of the COQ3 gene in Saccharomyces cerevisiae and catalyses the fourth step in the biosynthesis of ubiquinone (coenzyme Q) from p-hydroxybenzoic acid. A full-length cDNA encoding a mammalian homologue of DHHB-MTase was isolated from a newly constructed rat testis cDNA library by functional complementation of a coq3 deletion mutant of S. cerevisiae. The complementing clone contained a 1.1-kb poly(A)(+)-tailed insert with a 858-bp open reading frame and presumably encodes 3,4-dihydroxy-5-polyprenylbenzoate-MTase. The deduced rat amino acid (aa) sequence has a 39% identity over 138 aa with the yeast DHHB-MTase and a 37% identity over this same region with an Escherichia coli protein encoded by the ubiG gene, a MTase that catalyses the terminal step of ubiquinone biosynthesis. The rescue of the yeast coq3 mutant by the rat homologue suggests that yeast and rat synthesize ubiquinone via the same early steps in this pathway.
