The small ubiquitin-like modifier (SUMO) can form polymeric chains that are important signals in cellular processes such as meiosis, genome maintenance and stress response. The SUMO-targeted ubiquitin ligase RNF4 engages with SUMO chains on linked substrates and catalyses their ubiquitination, which targets substrates for proteasomal degradation. Here we use a segmental labelling approach combined with solution nuclear magnetic resonance (NMR) spectroscopy and biochemical characterization to reveal how RNF4 manipulates the conformation of the SUMO chain, thereby facilitating optimal delivery of the distal SUMO domain for ubiquitin transfer. SUMO forms flexible polymeric chains that can interact with ubiquitin ligases, such as RNF4. Here Xu et al. have used NMR spectroscopy and biochemical experiments to investigate the interaction between SUMO and RNF4, and propose a mechanism for delivery of substrates to the ubiquitination machinery.
