The enzyme methylates both eukaryotic substrates demethylubiquinol-3 (this activity is classified as EC 2.1.1.64) and 3,4-dihydroxy-5-farnesylbenzoic acid and the distinct prokaryotic substrate 3-((2E,6E)-farnesyl)benzene-1,2-diol Homo sapiens ? - ? 89 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-((2E,6E)-farnesyl)benzoate - Rattus norvegicus S-adenosyl-L-homocysteine + 5-((2E,6E)-farnesyl)-4-hydroxy-3-methoxybenzoate - ? 410189 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-(2E,6E)-farnesylbenzoate - Saccharomyces cerevisiae S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-5-farnesylbenzoate - ? 410190 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-(2E,6E)-farnesylbenzoate in vitro assay Homo sapiens S-adenosyl-L-homocysteine + 5-(2E,6E)-farnesyl-4-hydroxy-3-methoxybenzoate - ? 410191 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-hexaprenylbenzoate - Saccharomyces cerevisiae S-adenosyl-L-homocysteine + 5-all-trans-hexaprenyl-4-hydroxy-3-methoxybenzoate - ? 407322 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-hexaprenylbenzoate 3,4-dihydroxy-5-all-trans-hexaprenylbenzoate is an intermediate in biosynthesis of ubiquinone-6 in Saccharomyces cerevisiae (that is methylated by the yeast enzyme CoQ3 to 4-hydroxy-3-methoxy-5-hexaprenylbenzoate). When expressed in multicopy, the human construct rescues the growth of a yeast coq3 null mutant on a nonfermentable carbon source and restores coenzyme Q biosynthesis, although at lower levels than that of wild type yeast Homo sapiens S-adenosyl-L-homocysteine + 5-all-trans-hexaprenyl-4-hydroxy-3-methoxybenzoate - ? 407322 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-polyprenylbenzoate - Homo sapiens S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-5-all-trans-polyprenylbenzoate - ? 432926 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-polyprenylbenzoate - Caenorhabditis elegans S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-5-all-trans-polyprenylbenzoate - ? 432926 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-polyprenylbenzoate - Escherichia coli S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-5-all-trans-polyprenylbenzoate - ? 432926 2.1.1.114 S-adenosyl-L-methionine + 3,4-dihydroxy-5-all-trans-polyprenylbenzoate - Caenorhabditis elegans N2 S-adenosyl-L-homocysteine + 3-methoxy-4-hydroxy-5-all-trans-polyprenylbenzoate - ? 432926
