In enzymology, a D-tryptophan N-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + D-tryptophan CoA + N-acetyl-D-tryptophan Thus, the two substrates of this enzyme are acetyl-CoA and D-tryptophan, whereas its two products are CoA and N-acetyl-D-tryptophan. 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 acetyl-CoA:D-tryptophan N-acetyltransferase. Other names in common use include D-tryptophan acetyltransferase, and acetyl-CoA-D-tryptophan-alpha-N-acetyltransferase. References EC 2.3.1 Enzymes of unknown structure
