In enzymology, a tryptophan dimethylallyltransferase ({{EC number|2.5.1.34}}) is an enzyme that catalyzes the chemical reaction

:dimethylallyl diphosphate + L-tryptophan $\backslash rightleftharpoons$ diphosphate + 4-(3-methylbut-2-enyl)-L-tryptophan

Thus, the two substrates of this enzyme are dimethylallyl diphosphate and L-tryptophan, whereas its two products are diphosphate and 4-(3-methylbut-2-enyl)-L-tryptophan.

This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is {{chem name|dimethylallyl-diphosphate:L-tryptophan dimethylallyltransferase}}. Other names in common use include {{chem name|dimethylallylpyrophosphate:L-tryptophan dimethylallyltransferase}}, {{chem name|dimethylallyltryptophan synthetase}}, {{chem name|dimethylallylpyrophosphate:tryptophan dimethylallyl transferase}}, DMAT synthetase, and {{chem name|4-(gamma,gamma-dimethylallyl)tryptophan synthase}}.
