In enzymology, an aralkylamine N-acetyltransferase (EC 2.3.1.87) is an enzyme that catalyzes the chemical reaction

acetyl-CoA + a 2-arylethylamine \rightleftharpoons CoA + an N-acetyl-2-arylethylamine

Thus, the two substrates of this enzyme are acetyl-CoA and 2-arylethylamine, whereas its two products are CoA and N-acetyl-2-arylethylamine.

This enzyme belongs to the family of transferases, to be specific, those acyltransferases transferring groups other than aminoacyl groups. This enzyme participates in tryptophan metabolism.
