DE   3-demethylubiquinol 3-O-methyltransferase.
AN   2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone
AN   methyltransferase.
AN   3-demethylubiquinone-9 3-methyltransferase.
AN   5-demethylubiquinone-9 methyltransferase.
CA   a 3-demethylubiquinol + S-adenosyl-L-methionine = a ubiquinol + H(+) +
CA   S-adenosyl-L-homocysteine.
CC   -!- This enzyme is involved in ubiquinone biosynthesis.
CC   -!- Ubiquinones from different organisms have a different number of
CC       prenyl units (for example, ubiquinone-6 in Saccharomyces, ubiquinone-
CC       9 in rat and ubiquinone-10 in human), and thus the natural substrate
CC       for the enzymes from different organisms has a different number of
CC       prenyl units.
CC   -!- However, the enzyme usually shows a low degree of specificity
CC       regarding the number of prenyl units.
CC   -!- For example, the human COQ3 enzyme can restore biosynthesis of
CC       ubiquinone-6 in coq3 deletion mutants of yeast.
CC   -!- The enzymes from yeast, Escherichia coli and rat also catalyze the
CC       methylation of 3,4-dihydroxy-5-all-trans-polyprenylbenzoate (a
CC       reaction that is classified as EC 2.1.1.114).
