Accepted Name
Phloroisovalerophenone synthase.
Alternative Name(s)
3-methyl-1-(trihydroxyphenyl)butan-1-one synthase.

Comment(s)
  • Closely related to EC 2.3.1.74.
  • 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).
