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