Requires Mg2+. This membrane-bound protein is located in the plastids . In addition to naringenin, the enzyme can prenylate several other flavanones at the C-8 position, but more slowly. Along with EC 22.214.171.124 (8-dimethylallylnaringenin 2'-hydroxylase) and EC 126.96.36.199 (leachianone-G 2''-dimethylallyltransferase), this enzyme forms part of the sophoraflavanone-G-biosynthesis pathway.
Characterization of leachianone G 2"-dimethylallyltransferase, a novel prenyl side-chain elongation enzyme for the formation of the lavandulyl group of sophoraflavanone G in Sophora flavescens Ait. cell suspension cultures.
