The molecular principles of N-end rule recognition


The N-end rule pathway is a proteolytic system in which recognition components (N-recognins) recognize a set of N-terminal residues as part of degradation signals (N-degrons). Two studies in this issue report the structures of Ubr boxes, a substrate recognition domain of eukaryotic N-recognins. We discuss how eukaryotic and prokaryotic N-recognins use a… (More)
