| EC_number | 2.5.1.93 |
4-hydroxybenzoate geranyltransferase (, PGT1, PGT2, 4HB geranyltransferase, 4HB:geranyltransferase, p-hydroxybenzoate geranyltransferase, PHB geranyltransferase, geranyl diphosphate:4-hydroxybenzoate geranyltransferase) is an enzyme with systematic name geranyl-diphosphate:4-hydroxybenzoate 3-geranyltransferase. This enzyme catalyses the following chemical reaction
: geranyl diphosphate + 4-hydroxybenzoate \rightleftharpoons 3-geranyl-4-hydroxybenzoate + diphosphate
The enzyme is involved in shikonin biosynthesis. It has a strict substrate specificity for geranyl diphosphate and an absolute requirement for Mg2+.
