Definition:Catalysis of the reaction: a 2-methoxy-6-all-trans-polyprenyl-1,4-benzoquinol + S-adenosyl-L-methionine = a 6-methoxy-3-methyl-2-all-trans-polyprenyl-1,4-benzoquinol + S-adenosyl-L-homocysteine + H+.
Comment:Note that the polyprenyl sidechain substrate for this reaction has a different number of prenyl units in different organisms (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.
Synonyms:exact_synonym: 2-polyprenyl-6-methoxy-1,4-benzoquinone methylase activity;   2-polyprenyl-6-methoxy-1,4-benzoquinone methyltransferase activity;   coenzyme Q biosynthesis methyltransferase activity;   coenzyme Q biosynthetic process methyltransferase activity
 broad_synonym: ubiquinone biosynthesis methyltransferase activity;   ubiquinone biosynthetic process methyltransferase activity
