Biphenyl synthase

In enzymology, a biphenyl synthase is an enzyme that catalyzes the chemical reaction:


 * 3 malonyl-CoA + benzoyl-CoA $$\rightleftharpoons$$ 4 CoA + 3,5-dihydroxybiphenyl + 4 CO2

Thus, the two substrates of this enzyme are malonyl-CoA and benzoyl-CoA, whereas its three products are CoA, 3,5-dihydroxybiphenyl, and CO2.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is malonyl-CoA:benzoyl-CoA malonyltransferase. This enzyme is also called BIS.
