Term:polyprenyldihydroxybenzoate methyltransferase activity

Accession:GO:0010420 term browser browse the term
Definition:Catalysis of the reaction: a 3,4-dihydroxy-5-all-trans-polyprenylbenzoate + S-adenosyl-L-methionine = a 3-methoxy,4-hydroxy-5-all-trans-polyprenylbenzoate + 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: 3,4-dihydroxy-5-polyprenylbenzoic acid O-methyltransferase activity
