ENZYME entry: EC

Accepted Name
Phloroisovalerophenone synthase.
Alternative Name(s)
3-methyl-1-(trihydroxyphenyl)butan-1-one synthase.
Valerophenone synthase.
Reaction catalysed
Isovaleryl-CoA + 3 malonyl-CoA <=> 4 CoA + 3 CO(2) + 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one
  • Closely related to EC
  • The product, 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one, is phloroisovalerophenone.
  • Also acts on isobutyryl-CoA as substrate to give phlorisobutyrophenone.
  • The products are intermediates in the biosynthesis of the bitter (alpha) acids in hops (Humulus lupulus).
