EC 2.5.1.125     
Accepted name: 7-geranyloxy-5-hydroxy-2-methoxy-3-methylnaphthalene-1,4-dione synthase
Reaction: geranyl diphosphate + 2-O,3-dimethylflaviolin = diphosphate + 7-O-geranyl-2-O,3-dimethylflaviolin
Glossary: flaviolin = 2,5,7-trihydroxy-1,4-naphthoquinone
2-O,3-dimethylflaviolin = 5,7-dihydroxy-2-methoxy-3-methylnaphthalene-1,4-dione
7-O-geranyl-2-O,3-dimethylflaviolin = 7-{[(2E)-3,7-dimethylocta-2,6-dien-1-yl]oxy}-5-hydroxy-2-methoxy-3-methylnaphthalene-1,4-dione
Other name(s): Fur7
Systematic name: geranyl diphosphate:2-O,3-dimethylflaviolin geranyltransferase (7-O-geranyl-2-O,3-dimethylflaviolin-forming)
Comments: The enzyme is involved in furaquinocin biosynthesis in the bacterium Streptomyces sp. KO-3988. It catalyses the transfer of a geranyl group to 2-O,3-dimethylflaviolin to yield 7-O-geranyl-2-O,3-dimethylflaviolin and 6-linalyl-2-O,3-dimethylflaviolin (cf. EC 2.5.1.124, 6-linalyl-2-O,3-dimethylflaviolin synthase) in a 1:10 ratio.
