Figure 1.
Crystal structure of the Twf-C–actin monomer complex at 2.55 Å resolution. (A) Twf-C (blue) binds between the actin (green) subdomains 1 and 3, and buries a surface area of ∼1,200 Å2. The ATP molecule bound to actin is shown in atom colors. (B) The σA weighted 2 mFo-DFc electron density map around the ATP molecule contoured at 1 σ.
