[https://www.uniprot.org/uniprot/NAT1_SCHPO NAT1_SCHPO] Non-catalytic component of the NatA N-terminal acetyltransferase, which catalyzes acetylation of proteins beginning with Met-Ser, Met-Gly and Met-Ala. N-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 termini of nascent polypeptides for acetylation (By similarity).

N-terminal acetylation is ubiquitous among eukaryotic proteins and controls a myriad of biological processes. Of the N-terminal acetyltransferases (NATs) that facilitate this cotranslational modification, the heterodimeric NatA complex has the most diversity for substrate selection and modifies the majority of all N-terminally acetylated proteins. Here, we report the X-ray crystal structure of the 100-kDa holo-NatA complex from Schizosaccharomyces pombe, in the absence and presence of a bisubstrate peptide-CoA-conjugate inhibitor, as well as the structure of the uncomplexed Naa10p catalytic subunit. The NatA-Naa15p auxiliary subunit contains 13 tetratricopeptide motifs and adopts a ring-like topology that wraps around the NatA-Naa10p subunit, an interaction that alters the Naa10p active site for substrate-specific acetylation. These studies have implications for understanding the mechanistic details of other NAT complexes and how regulatory subunits modulate the activity of the broader family of protein acetyltransferases.
