ID 2.3.1.177 DE 3,5-dihydroxybiphenyl synthase. AN biphenyl synthase. AN BIS. CA benzoyl-CoA + 3 H(+) + 3 malonyl-CoA = biphenyl-3,5-diol + 4 CO2 + 4 CoA. CC -!- A polyketide synthase that is involved in the production of the CC phytoalexin aucuparin. CC -!- 2-hydroxybenzoyl-CoA can also act as substrate but it leads to the CC derailment product 4-hydroxycoumarin (cf. EC 2.3.1.208). CC -!- This enzyme uses the same starter substrate as EC 2.3.1.151. DR Q27Z07, BIPS1_SORAU; //
