Enzyme Information

3-demethylubiquinol 3-O-methyltransferase.
based on mapping to UniProt P39367
S-adenosyl-L-methionine + 3-demethylubiquinone-n = S-adenosyl-L- homocysteine + ubiquinone-n.
-!- This enzyme is involved in ubiquinone biosynthesis. -!- Ubiquinones from different organisms have a different number of prenyl units (for example, ubiquinone-6 in Saccharomyces, ubiquinone- 9 in rat and ubiquinone-10 in human), and thus the natural substrate for the enzymes from different organisms has a different number of prenyl units. -!- However, the enzyme usually shows a low degree of specificity regarding the number of prenyl units. -!- For example, the human COQ3 enzyme can restore biosynthesis of ubiquinone-6 in coq3 deletion mutants of yeast. -!- The enzymes from yeast, Escherichia coli and rat also catalyze the methylation of 3,4-dihydroxy-5-all-trans-polyprenylbenzoate (a reaction that is classified as EC 2.1.1.114).
