Figure 5-38The three-dimensional structure of ubiquitin

This protein contains 76 amino acid residues. The addition of a chain of ubiquitin molecules to a protein results in the degradation of this protein by the proteasome (see Figure 5-39). (Based on S. Vijay-Kumar, C.E. Bugg, K.D. Wilkinson, and W.J. Cook, Proc. Natl. Acad. Sci. USA 82:3582-3585, 1985.)
