In enzymology, a 3,4-dichloroaniline N-malonyltransferase (EC 2.3.1.114) is an enzyme that catalyzes the chemical reaction

malonyl-CoA + 3,4-dichloroaniline ${\displaystyle \rightleftharpoons }$ CoA + N-(3,4-dichlorophenyl)-malonamate

Thus, the two substrates of this enzyme are malonyl-CoA and 3,4-dichloroaniline, whereas its two products are CoA and N-(3,4-dichlorophenyl)-malonamate.

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:3,4-dichloroaniline N-malonyltransferase.
