Emerging Functions for N-Terminal Protein Acetylation in Plants

Abstract

N-terminal (Nt-) acetylation is a widespread but poorly understood co-translational protein modification. Two reports now shed light onto the proteome-wide dynamics and protein-specific consequences of Nt-acetylation in relation to plant development, stress-response, and protein stability, identifying this modification as a key regulator of diverse aspects of plant growth and behaviour.

Keywords: N-end rule; N-terminal acetylation; abscisic acid (ABA); drought stress; plant immunity; protein degradation.
