ID 2.5.1.125 DE 7-geranyloxy-5-hydroxy-2-methoxy-3-methylnaphthalene-1,4-dione synthase. CA (2E)-geranyl diphosphate + 2-O,3-dimethylflaviolin + H(+) = 7-O-geranyl- CA 2-O,3-dimethylflaviolin + diphosphate. CC -!- The enzyme is involved in furaquinocin biosynthesis in the bacterium CC Streptomyces sp. KO-3988. CC -!- It catalyzes the transfer of a geranyl group to 2-O,3- CC dimethylflaviolin to yield 7-O-geranyl-2-O,3-dimethylflaviolin and CC 6-linalyl-2-O,3-dimethylflaviolin (cf. EC 2.5.1.124) in a 1:10 ratio. DR Q2L6E3, FUR7_STREO ; //
