Figure 4.
Stereo diagrams of the homology model of S. pombe profilin
bound to actin based on the bovine profilin-β actin crystal
structure (PDB 1HLU). Color code for C-α traces: actin, dark
blue; bovine profilin, cyan; S. pombe profilin, tan. ATP is
yellow. Some residues discussed in the text are shown in stick
representation. Subdomains 1–4 of actin are labeled in panel
A. Important secondary structural elements are also labeled. The
figure in panel B is oriented to highlight the β4/β5 and
β5/β6 wings in bovine profilin. The figure was generated using
Molscript and Raster3D.
