FunFam 117: 4-hydroxycoumarin synthase 1

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
4-hydroxycoumarin synthase. [EC: 2.3.1.208]
Malonyl-CoA + 2-hydroxybenzoyl-CoA = 2 CoA + 4-hydroxycoumarin + CO(2).
  • The enzyme, a polyketide synthase, can also accept benzoyl-CoA as substrate, which it condenses with 3 malonyl-CoA molecules to form 3,5-dihydroxybiphenyl (cf. EC 2.3.1.177).
 2 D2DRC4 D2DRC5
3,5-dihydroxybiphenyl synthase. [EC: 2.3.1.177]
3 malonyl-CoA + benzoyl-CoA = 4 CoA + 3,5-dihydroxybiphenyl + 4 CO(2).
  • A polyketide synthase that is involved in the production of the phytoalexin aucuparin.
  • 2-hydroxybenzoyl-CoA can also act as substrate but it leads to the derailment product 4-hydroxycoumarin (cf. EC 2.3.1.208).
  • This enzyme uses the same starter substrate as EC 2.3.1.151.
