In yeast, the evolutionarily conserved GID E3 ligase mediates glucose-induced ...Protein degradation, a major eukaryotic response to cellular signals, is subject to numerous layers of regulation. In yeast, the evolutionarily conserved GID E3 ligase mediates glucose-induced degradation of fructose-1,6-bisphosphatase (Fbp1), malate dehydrogenase (Mdh2), and other gluconeogenic enzymes. "GID" is a collection of E3 ligase complexes; a core scaffold, RING-type catalytic core, and a supramolecular assembly module together with interchangeable substrate receptors select targets for ubiquitylation. However, knowledge of additional cellular factors directly regulating GID-type E3s remains rudimentary. Here, we structurally and biochemically characterize Gid12 as a modulator of the GID E3 ligase complex. Our collection of cryo-EM reconstructions shows that Gid12 forms an extensive interface sealing the substrate receptor Gid4 onto the scaffold, and remodeling the degron binding site. Gid12 also sterically blocks a recruited Fbp1 or Mdh2 from the ubiquitylation active sites. Our analysis of the role of Gid12 establishes principles that may more generally underlie E3 ligase regulation. #1: Journal: Mol Cell / Year: 2021Title: GID E3 ligase supramolecular chelate assembly configures multipronged ubiquitin targeting of an oligomeric metabolic enzyme Authors: Sherpa, D. / Chrustowicz, J. / Qiao, S. / Langlois, C.R. / Hehl, L.A. / Gottemukkala, K.V. / Hansen, F.M. / Karayel, O. / von Gronau, S. / Prabu, J.R. / Mann, M. / Alpi, A.F. / Schulman, B.A. | |||||||||||||||||||||||||||
