IUBMB Enzyme Nomenclature

EC 2.3.1.208

Accepted name: 4-hydroxycoumarin synthase

Reaction: malonyl-CoA + 2-hydroxybenzoyl-CoA = 2 CoA + 4-hydroxycoumarin + CO2

For diagram of reaction click here.

Glossary: 2-hydroxybenzoyl-CoA = salicyloyl-CoA

Other name(s): BIS2; BIS3

Systematic name: malonyl-CoA:2-hydroxybenzoyl-CoA malonyltransferase

Comments: 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, biphenyl synthase) [1].
