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 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...

TranscriptomicsPositional proteomics reveals differences in N-terminal proteoform stability
To understand the impact of alternative translation initiation on a proteome, we performed the first study on protein turnover using positional proteomics and ribosome profiling to distinguish between N-terminal proteoforms of individual genes. Overall, we monitored the stability of 1,941 human N-te...

ProteomicsSelective enrichment of N-terminal proline peptides via hydrazide chemistry for proteomics analysis
A challenge for shotgun proteomics is the identification of low abundance proteins, which is always hampered owing to the extreme complexity of protein digests and highly dynamic concentration range of proteins. To reduce the complexity of the peptide mixture, we developed a novel method to selectiv...

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...

ProteomicsChemical proteomics profiling of N-terminal and lysine 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 ...

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...

Proteogenomics is a research field where proteome data is used to improve gene annotation. To achieve this, customized protein databases are constructed to match proteomic data. We perform a proteogenomic analysis using N-terminal COFRADIC data in order to identify novel translational initiation sta...
