N-terminal acetylation is a conserved protein modification among eukaryotes, and the yeast Saccharomyces cerevisiae is a valuable model system for studying this modification. The enzymes responsible for the bulk of protein N-terminal acetylation in S. cerevisiae are the N-terminal acetyltransferases...

Acetylation of amino groups is a prevalent protein modification in all kingdoms of life. Acetyl groups are transferred from Coenzyme A (CoA) to protein N-termini and lysine side chains by N-terminal acetyltransferases (NATs) and lysine acetyltransferases (KATs), respectively. Building on lysine-CoA ...

Protein ⍺-N-methylation is a cryptic and relatively unexplored post-translational modification involving the covalent addition of methyl groups to the free a-amino group at protein N-termini. To systematically explore the extent of ⍺-N-terminal methylation in yeast and humans, we utilized a repurpos...

N-terminal (Nt) acetylation, catalyzed by N-terminal acetyltransferases (NATs), has emerged as an important co-translational modification in eukaryotes, and involves the transfer of the acetyl moiety from acetyl-CoA (Ac-CoA) to the α-amino group of a nascent polypeptide. Here, we report the first gl...

Excision of the N-terminal initiator methionine (iMet) from nascent peptide chains is an essential and omnipresent protein modification carried out by Methionine aminopetidases (MetAPs) and accounting for a major source of N-terminal proteoform diversity. While MetAP2 is known to be implicated in pr...

To understand the impact of alternative translation initiation on a proteome, we performed the first large-scale study of protein turnover rates in which we distinguish between N-terminal proteoforms pointing to translation initiation events. Using pulsed SILAC combined with N-terminal COFRADIC we m...

Removal of the N-terminal formyl group on nascent proteins by peptide deformylase (PDF) is the most prevalent protein modification in bacteria that impacts over 90% of the proteome. PDF is essential and a critical target of antibiotic development; however, its role in bacterial physiology remains a ...

System-wide analyses reveal essential roles of N-terminal protein modification in bacterial physiology
Protein acetylation is a universally conserved modification occurring on N-termini (N-Terminal acetylation, NTA). Although recent reports indicate that NTA occur frequently in plant plastids, little is known about the machinery involved in plastid acetylation and why these modifications are that fre...
