<p>This group represents N-terminal acetyltransferase A (NatA) auxiliary subunit and represents a non-catalytic component of the NatA N-terminal acetyltransferase, which catalyzes acetylation of proteins beginning with Met-Ser, Met-Gly and Met-Ala.</p><p>N-terminal acetylation plays a role in normal eukaryotic translation and processing, protect against proteolytic degradation and protein turnover. NAT1 anchors ARD1 and NAT5 to the ribosome and may present the N- terminal of nascent polypeptides for acetylation [<cite idref="PUB00053448"/>], [<cite idref="PUB00053449"/>].</p> Alpha-acetyltransferase 15, NatA
