Entry Name 3,5-dihydroxybiphenyl synthase;
Class Transferases;BRITE hierarchy
Sysname malonyl-CoA:benzoyl-CoA malonyltransferase
Reaction(IUBMB) 3 malonyl-CoA + benzoyl-CoA = 4 CoA + 3,5-dihydroxybiphenyl + 4 CO2 [RN:
R09621 ]
Reaction(KEGG) Substrate Product Comment 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 , 4-hydroxycoumarin synthase) [2]. This enzyme uses the same starter substrate as EC
2.3.1.151 , benzophenone synthase.
History EC 2.3.1.177 created 2006, modified 2012
