| Glossary: | dimethylallyl = prenyl = 3-methylbut-2-en-1-yl isopentenyl = 3-methylbut-3-en-1-yl lavandulyl = 5-methyl-2-(prop-1-en-2-yl)hex-4-en-1-yl leachianone G = (–)-(2S)-2′-hydroxy-8-prenylnaringenin = (–)-(2S)-2-(2,4-dihydroxyphenyl)-5,7-dihydroxy-8-(3-methylbut-2-en-1-yl)-2,3-dihydro-4H-chromen-4-one sophoraflavanone G = (2S)-2-(2,4-dihydroxyphenyl)-5,7-dihydroxy-8-[(2R)-5-methyl-2-(prop-1-en-2-yl)hex-4-en-1-yl]-2,3-dihydro-4H-chromen-4-one |

| 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 | ||
| Comments: | 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. | ||
