Sysname
geranyl-diphosphate:4-hydroxybenzoate 3-geranyltransferase
Reaction(IUBMB)
geranyl diphosphate + 4-hydroxybenzoate = 3-geranyl-4-hydroxybenzoate + diphosphate [RN:R09040]
Reaction(KEGG)
Substrate
geranyl diphosphate [CPD:C00341];
4-hydroxybenzoate [CPD:C00156]
Product
3-geranyl-4-hydroxybenzoate;
diphosphate [CPD:C00013]
Comment
The enzyme is involved in shikonin biosynthesis. It has a strict substrate specificity for geranyl diphosphate and an absolute requirement for Mg2+ [2].
