a·cet·y·lase

(a-sĕt'il-ās),
Any enzyme catalyzing acetylation or deacetylation, as in the formation of N-acetylglutamate from glutamate plus acetyl-CoA, or the reverse; acetylases are usually called acetyltransferases.

This increase in acetylation may result either from a decrease in the activity of the enzyme that removes acetyl groups (i.e., histone deacetylase) or an increase in the activity of the enzyme that adds acetyl groups (i.e., histone acetylase).

First, a DNA fragment spanning 1212 bp, which contained the whole coding region of the NAT2 gene, was amplified from genomic DNA from study samples by use of primers specifically designed to amplify the NAT2 gene, avoiding amplification of the highly homologous genes N-acetyltransferase 1 (arylamine N-acetyltransferase) (NATI) and arylamide acetylase pseudogene (AACP; also known as NATP) (7).
