ID   2.3.1.156
DE   phloroisovalerophenone synthase.
AN   3-methyl-1-(trihydroxyphenyl)butan-1-one synthase.
AN   acylphloroglucinol synthase.
AN   valerophenone synthase.
CA   (1) 3-methylbutanoyl-CoA + 3 H(+) + 3 malonyl-CoA = 3 CO2 + 4 CoA +
CA   phlorisovalerophenone.
CA   (2) 2-methylpropanoyl-CoA + 3 H(+) + 3 malonyl-CoA = 3 CO2 + 4 CoA +
CA   phlorisobutanophenone.
CC   -!- Closely related to EC 2.3.1.74.
CC   -!- Also acts on isobutyryl-CoA as substrate to give
CC       phlorisobutyrophenone.
CC   -!- The products are intermediates in the biosynthesis of the bitter
CC       acids in hops (Humulus lupulus) and glucosides in strawberry
CC       (Fragaria X ananassa).
CC   -!- It is also able to generate naringenin chalcone from 4-coumaroyl-CoA.
