ENZYME entry: EC 2.3.1.253

Accepted Name
phloroglucinol synthase
Reaction catalysed
3 H(+) + 3 malonyl-CoA <=> 1,3,5-trihydroxybenzene + 3 CO2 + 3 CoA
Comment(s)
  • The enzyme, characterized from the bacterium Pseudomonas protegens Pf-5, is a type III polyketide synthase.
  • The mechanism involves the cyclization of an activated 3,5- dioxoheptanedioate intermediate.
  • The enzyme exhibits broad substrate specificity, and can accept C4-C12 aliphatic acyl-CoAs and phenylacetyl-CoA as the starter molecules, forming C(6)-polyoxoalkylated alpha-pyrones by sequential condensation with malonyl-CoA.
