2.3.1.212 | additional information | RiPKS4 is a bifunctional polyketide synthase producing both 4-hydroxybenzalacetone and naringenin chalcone, the latter by reaction of chalcone synthase, EC 2.3.1.74. The recombinant RiPKS4 protein, like the native protein from raspberry fruits accepts 4-coumaryl-CoA and ferulyl-CoA as starter substrates and catalyzes the formation of both naringenin chalcone, 4-hydroxy-benzalacetone, and 3-methoxy-4-hydroxy-benzalacetone. The activity of RiPKS4 is higher with ferulyl-CoA than with 4-coumaryl-CoA | Rubus idaeus | ? | - |
