EC 2.5.1.71 Details
EC number
2.5.1.71
Accepted name
leachianone-G 2′′-dimethylallyltransferase
Reaction
prenyl diphosphate + leachianone G = diphosphate + sophoraflavanone G
Other name(s)
LG 2′′-dimethylallyltransferase, leachianone G 2′′-dimethylallyltransferase, LGDT, dimethylallyl-diphosphate:leachianone-G 2′′-dimethylallyltransferase
Systematic name
prenyl-diphosphate:leachianone-G 2′′-prenyltransferase
Comment
This membrane-bound enzyme is located in the plastids and requires Mg2+ for activity. The reaction forms the lavandulyl sidechain of sophoraflavanone G by transferring a prenyl group to the 2′′ position of another prenyl group attached at position 8 of leachianone G. The enzyme is specific for prenyl diphosphate as the prenyl donor, as it cannot be replaced by isopentenyl diphosphate or geranyl diphosphate. Euchrenone a7 (a 5-deoxy derivative of leachianone G) and kenusanone I (a 7-methoxy derivative of leachianone G) can also act as substrates, but more slowly. Along with EC 1.14.14.142 (8-dimethylallylnaringenin 2′-hydroxylase) and EC 2.5.1.70 (naringenin 8-dimethylallyltransferase), this enzyme forms part of the sophoraflavanone-G-biosynthesis pathway.
