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...

Proteomicsplasma membrane anchored NAA60 N-terminal acetylation profiling 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. AtNAA60 localizes to the plasma membrane in vivo by an α-helical membrane anchor at its C-terminus. In this study, we investigated the Arabidopsis th...

N-terminal acetylation is one of the most abundant protein modifications in eukaryotes and is catalysed in humans by seven N-terminal acetyltransferases. AtNAA50 interreact with the NatA complex (NAA10 and NAA15) to form the NatE complex. In this study, we investigated the Arabidopsis thaliana N-ter...

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...

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...

The ribosome-tethered N-terminal acetyltransferase A (NatA) acetylates 52% of soluble proteins in Arabidopsis thaliana. This co-translational shielding of the N-terminus stabilizes diverse cytosolic plant proteins. The Huntingtin yeast partner K (HYPK) facilitates NatA activity in planta, but in vit...
