Metabolite Identification
Common Name2-Hexaprenyl-6-methoxy-1,4-benzoquinone
Description2-Hexaprenyl-6-methoxy-1,4-benzoquinone is involved in the ubiquinone biosynthesis pathway. 2-Hexaprenyl-6-methoxy-1,4-benzoquinone is created from 2-Hexaprenyl-6-methoxyphenol by ubiquinone biosynthesis monooxygenase Coq6 [EC:1.14.13.-]. 2-Hexaprenyl-6-methoxy-1,4-benzoquinone is then converted into 2-Hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinone by ubiquinone biosynthesis methyltransferase [EC:2.1.1.-].
