Figure 1.
Figure 1. A new conformation of Lys48-linked tetraubiquitin. The tetraubiquitin coloring from proximal ubiquitin to distal ubiquitin is: yellow–cyan–green–blue (1–2–3–4). Rotating 45° in either direction about the x-axis from the center structure shows the interface of the two diubiquitin subunits (1–2 on the left, 3–4 on the right). Figure 1.
