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...

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...

Abstract still has to be written. The obtained peptide mixtures were introduced into an LC-MS/MS system, the Ultimate 3000 (Dionex, Amsterdam, The Netherlands) in-line connected to an LTQ Orbitrap XL mass spectrometer (Thermo Fisher Scientific, Bremen, Germany). Samples were first loaded on a trapp...

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...

ProteomicsN-terminomics Proteogenomics - N-terminal proteomics assisted profiling of the unexplored translation initiation landscape in Arabidopsis thaliana
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...

ProteomicsREPARATION: Ribosome Profiling Assisted (Re-) Annotation of Bacterial genomes - PART 2
Prokaryotic genome annotation is highly dependent on automated methods, as manual curation cannot keep up with the exponential growth of sequenced genomes. Current automated techniques depend heavily on sequence context and often underestimate the complexity of the proteome. We developed REPARATION ...

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...
