ProteomicsGlobal and protein-specific analysis reveals Nt-acetylation-independent turnover of SQE1 by Arabidopsis DOA10-like E3 ligases
The Acetylation-dependent (Ac/) N-degron pathway degrades proteins through recognition of their acetylated N-termini (Nt) by specific E3-ligases (Ac/N-recognins). To date, no Ac/N-recognins have been defined in plants. Here we use molecular, genetic, and multi-omics approaches to characterise potent...

ProteomicsLoss of N-terminal acetyltransferase A activity induces thermally unstable ribosomal proteins and increases their turnover
Protein N-terminal (Nt) acetylation is one of the most abundant modifications in eukaryotes, covering ~50-80 % of the proteome, depending on species. Cells with defective Nt-acetylation display a wide array of phenotypes such as impaired growth, mating defects and increased stress sensitivity. Howev...

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...

ProteomicsDifferential N-terminal COFRADIc analyses of Ogden fibroblasts
The X-linked lethal Ogden syndrome was the first reported human genetic disorder associated with a mutation in an N-terminal acetyltransferase gene. The affected males harbour a Ser37Pro mutation in the gene encoding hNaa10, the catalytic subunit of NatA, themajor human NAT. In order to understand t...

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...

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...

N-degron pathway plays an important role in the protein quality control and maintenance of cellular protein homeostasis. ZER1 and ZYG11B, the substrate receptors of the Cullin 2-RING E3 ubiquitin ligase (CRL2), recognize N-terminal (Nt) glycine degrons and participate in the Nt-myristoylation qualit...
