Sysname
prenyl-diphosphate:naringenin 8-prenyltransferase
Reaction(IUBMB)
prenyl diphosphate + (-)-(2S)-naringenin = diphosphate + sophoraflavanone B [RN:R08951]
diphosphate [CPD:C00013];
sophoraflavanone B [CPD:C18023]
Comment
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 1.14.14.142 (8-dimethylallylnaringenin 2'-hydroxylase) and EC 2.5.1.71 (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.
