ProteomicsN-terminal acetylome analysis reveals an expanded substrate profile for the NatC N-terminal acetyltransferase complex in yeast
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...

ProteomicsPositional proteomics reveals differences in N-terminal proteoform stability.
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...

ProteomicsMetabolic regulation of N-terminal acetylation in yeast
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...

ProteomicsN-terminal acetylome analyses reveals the substrate specificity profile of Naa50 (Nat5) and implicate NATs in influencing initiator Methionine processing
Co-translational N-terminal (Nt-) acetylation of nascent polypeptides is catalyzed by N-terminal acetyltransferases (NATs). The very N-terminal amino acid sequence is the major factor determining whether or not a given protein is Nt-acetylated. In humans, six different NATs, denoted NatA-NatF, are i...

ProteomicsAn OMICS perspective on N-terminal Methionine Excision
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...

ProteomicsN-terminal acetylation by NatB in Arabidopsis thaliana
N-terminal acetylation (NTA) is one of the most abundant protein modifications in eukaryotes and is catalysed in humans by seven N-acetyltransferases. In this study, we investigated the Arabidopsis thaliana NatB catalytic (NAA20) and auxiliary subunit (NAA25) and their influence on protein N-termina...

ProteomicsDPP8/9 processing of human AK2 unmasks an IAP binding motif
AK2 is n-terminally processed by methionine aminopeptidases, N-terminal acetylation and DDP8/9 to become an active protein which is then sorted in the mitochondrial intermembrane space. We used peptide pull-downs of free and acetylated N-terminal peptides of AK2 from the different processing steps t...

ProteomicsGlobal acetylation profiling for multiple Arabidopsis thaliana plastid N-terminal acetyltransferases
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...

The study was conducted to elucidate potential cleavage sites of GPR125 which are known to undergo N-terminal shedding through autoproteolysis in a region different to other GRPs. To do these different enzymatic strategies as well as enrichment of both N-terminal and C-terminal peptides, was conduct...
