In enzymology a histidine N-acetyltransferase (EC 2.3.1.33) is an enzyme that catalyzes the chemical reactionacetyl-CoA + L-histidine CoA + N-acetyl-L-histidineThus the two substrates of this enzyme are acetyl-CoA and L-histidine whereas its two products are CoA and N-acetyl-L-histidine.This enzyme belongs to the family of transferases specifically those acyltransferases transferring groups other than aminoacyl groups.
