In enzymology, a leucine N-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + L-leucine CoA + N-acetyl-L-leucine Thus, the two substrates of this enzyme are acetyl-CoA and L-leucine, whereas its two products are CoA and N-acetyl-L-leucine. 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:L-leucine N-acetyltransferase. This enzyme is also called leucine acetyltransferase. References EC 2.3.1 Enzymes of unknown structure
