In enzymology, a histidine N-acetyltransferase (EC 2.3.1.33) is an enzyme that catalyzes the chemical reaction
- acetyl-CoA + L-histidine CoA + N-acetyl-L-histidine
Thus, 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. The systematic name of this enzyme class is acetyl-CoA:L-histidine N-acetyltransferase. Other names in common use include acetylhistidine synthetase, and histidine acetyltransferase.
