Benzophenone synthase

In enzymology, a benzophenone synthase (EC 2.3.1.151) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are malonyl-CoA and 3-hydroxybenzoyl-CoA, whereas its 3 products are CoA, 2,3',4,6-tetrahydroxybenzophenone, 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:3-hydroxybenzoyl-CoA malonyltransferase.
