Accepted name: naringenin 8-dimethylallyltransferase
Reaction: dimethylallyl diphosphate + (-)-(2S)-naringenin = diphosphate + sophoraflavanone B
For diagram of sophoraflavanone-G biosynthesis, click here
Glossary: (-)-(2S)-naringenin = (-)-(2S)-5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-one
sophoraflavanone B = (-)-(2S)-8-dimethylallylnaringenin = (-)-(2S)-5,7-dihydroxy-2-(4-hydroxyphenyl)-8-(3-methylbut-2-enyl)chroman-4-one
Other name(s): N8DT
Systematic name: dimethylallyl-diphosphate:naringenin 8-dimethylallyltransferase
Comments: Requires Mg2+. This membrane-bound protein is located in the plastids [2]. In addition to naringenin, the enzyme can prenylate several other flavanones at the C-8 position, but more slowly. Along with EC (8-dimethylallylnaringenin 2′-hydroxylase) and EC (leachianone G 2′′-dimethylallyltransferase), this enzyme forms part of the sophoraflavanone-G-biosynthesis pathway.
