NMR structure of HYB^ΔC (aa 106–194). A, superposition of 20 energy-minimized conformers representing the NMR structure of HYB^ΔC. B, ribbon diagram of the lowest-energy conformer representing the three-dimensional NMR structure of HYB^ΔC. Each monomer contains three zinc-coordination sites: Sites 1, 2, and 3. The zinc ions are shown as red spheres. C, metal coordinations in the NMR structure of HYB^ΔC. The coordination of zinc ions in the RING domain and the C-terminal domain of HYB^ΔC are shown.
