Metabolite Identification
Common Name2-Hexaprenyl-3-methyl-6-methoxy-1,4 benzoquinone
Description2-Hexaprenyl-3-methyl-6-methoxy-1,4 benzoquinone is involved in the ubiquinone biosynthesis pathway. 2-Hexaprenyl-3-methyl-6-methoxy-1,4 benzoquinone is created from 2-Hexaprenyl-6-methoxy-1,4-benzoquinone by ubiquinone biosynthesis methyltransferase [EC:2.1.1.-]. 2-Hexaprenyl-3-methyl-6-methoxy-1,4 benzoquinone is then converted to 2-Hexaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone by ubiquinone biosynthesis monooxygenase Coq7 [EC:1.14.13.-].
