6'-deoxychalcone synthase

6'-deoxychalcone synthase

In enzymology, a 6'-deoxychalcone synthase (EC number|2.3.1.170) is an enzyme that catalyzes the chemical reaction

:3 malonyl-CoA + 4-coumaroyl-CoA + NADPH + H+ ightleftharpoons 4 CoA + isoliquiritigenin + 3 CO2 + NADP+ + H2O

The 4 substrates of this enzyme are malonyl-CoA, 4-coumaroyl-CoA, NADPH, and H+, whereas its 5 products are CoA, isoliquiritigenin, CO2, NADP+, and H2O. Deoxychalcone synthase catalyzed activity is involved in the biosynthesis of retrochalcone and certain phytoalexins in the cells of glycyrrhiza echinata (Russian licorice) and other leguminous plants.

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:4-coumaroyl-CoA malonyltransferase (cyclizing, reducing).
