The molecular principles of N-end rule recognition

Nature Structural & Molecular Biology volume 17, pages 1164–1165 (2010)Cite this article

Subjects

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 similar molecular principle to recognize a different set of N-degrons.
