EC | 2.3.1.156 | ||||||
Accepted name: | phloroisovalerophenone synthase | ||||||
Reaction: | (1) isovaleryl-CoA + 3 malonyl-CoA = 4 CoA + 3 CO2 + phlorisovalerophenone (2) isobutyryl-CoA + 3 malonyl-CoA = 4 CoA + 3 CO2 + phlorisobutyrophenone |

Glossary: | phlorisobutyrophenone = 2-methyl-1-(2,4,6-trihydroxyphenyl)propan-1-one phlorisovalerophenone = 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one |
||||||
Other name(s): | valerophenone synthase; 3-methyl-1-(trihydroxyphenyl)butan-1-one synthase; acylphloroglucinol synthase; isovaleryl-CoA:malonyl-CoA acyltransferase | ||||||
Systematic name: | acyl-CoA:malonyl-CoA acyltransferase | ||||||
Comments: | Closely related to EC 2.3.1.74, naringenin-chalcone synthase. Also acts on isobutyryl-CoA as substrate to give phlorisobutyrophenone. The products are intermediates in the biosynthesis of the bitter acids in hops (Humulus lupulus) and glucosides in strawberry (Fragaria X ananassa). It is also able to generate naringenin chalcone from 4-coumaroyl-CoA. | ||||||

EC | 2.4.1.358 | ||||||
Accepted name: | acylphloroglucinol glucosyltransferase | ||||||
Reaction: | UDP-α-D-glucose + 2-acylphloroglucinol = UDP + 2-acylphloroglucinol 1-O-β-D-glucoside | ||||||
Glossary: | phlorisobutyrophenone = 2-methyl-1-(2,4,6-trihydroxyphenyl)propan-1-one phlorisovalerophenone = 3-methyl-1-(2,4,6-trihydroxyphenyl)butan-1-one |
||||||
Other name(s): | UGT71K3 | ||||||
Systematic name: | UDP-α-D-glucose:2-acylphloroglucinol 1-O-β-glucosyltransferase | ||||||
Comments: | Isolated from strawberries (Fragaria X ananassa). Acts best on phloroisovalerophenone and phlorobutyrophenone but will also glycosylate many other phenolic compounds. A minor product of the reaction is the 5-O-β-D-glucoside. | ||||||
