Name
7-geranyloxy-5-hydroxy-2-methoxy-3-methylnaphthalene-1,4-dione synthase;
Fur7
Class
Transferases;
Transferring alkyl or aryl groups, other than methyl groups;
Transferring alkyl or aryl groups, other than methyl groups (only sub-subclass identified to date)
BRITE hierarchy
Sysname
geranyl diphosphate:2-O,3-dimethylflaviolin geranyltransferase (7-O-geranyl-2-O,3-dimethylflaviolin-forming)
Reaction(IUBMB)
geranyl diphosphate + 2-O,3-dimethylflaviolin = diphosphate + 7-O-geranyl-2-O,3-dimethylflaviolin [RN:R11087]
Reaction(KEGG)
Substrate
geranyl diphosphate [CPD:C00341];
2-O,3-dimethylflaviolin [CPD:C21001]
Product
diphosphate [CPD:C00013];
7-O-geranyl-2-O,3-dimethylflaviolin [CPD:C21003]
Comment
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.
