dimethylallyl-diphosphate:naringenin 8-dimethylallyltransferase

dimethylallyl diphosphate + (-)-(2S)-naringenin = diphosphate + sophoraflavanone B [RN:R08951]

R08951
Reaction

dimethylallyl diphosphate [CPD:C00235];
(-)-(2S)-naringenin [CPD:C00509]

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 1.14.13.103 (8-dimethylallylnaringenin 2'-hydroxylase) and EC 2.5.1.71 (leachianone G 2''-dimethylallyltransferase), this enzyme forms part of the sophoraflavanone-G-biosynthesis pathway.

EC 2.5.1.70 created 2007
