Metabolite Identification
Common Name2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone
Description2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone is involved in the ubiquinone biosynthesis pathway. 2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone is created from 2-Hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinone by ubiquinone biosynthesis monooxygenase Coq7 [EC:1.14.13.-]. 2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone is then converted to ubiquinone by hexaprenyldihydroxybenzoate methyltransferase [EC:2.1.1.114].
