Figure 2
The structure of the Dsk2 UBL domain. (a) Stereo diagram of part of the 1.15 Å resolution σA-weighted 2Fo − Fc electron-density map contoured at 0.48 e Å−3. Parts of β-strands β1, β5, β3 and β4 are shown. This figure and others were produced with AESOP (Martin Noble, unpublished program). (b) Schematic diagram of the Dsk2 UBL domain coloured blue to red from the the N-terminus to the C-terminus. Secondary-structural elements are labelled. β1, L3–S9; β2, D12–V18; α1, T23–G36; β3, N41–Y46; β4, K49–L51; 310, E58–H61; β5, Q65–S73. (c) Comparison of the structure of Dsk2 UBL (coloured blue to red) with Ub (yellow). The major differences are in the loop between β1 and β2 (where the side chains of UBL residues 8–10 and Ub residues 6–9 are shown) and the C-terminal region. (d) The aligned sequences of UBL domains from S. cerevisiae Dsk2, S. cerevisiae Rad23, human PLIC2 and human ubiquitin. The secondary-structural elements for Dsk2 UBL are shown as rectangles for α-helices and arrows for β-strands. The symbols * and . below the sequences indicate identical and similar residues, respectively. Residues that contact the UBA domain in the UBA–UBL complex are highlighted in green. |
