Figure 7
Exemplary 2mFoDFc electron densities at 1.5σ for the structures of proteinase K (a) and thermolysin (b) derived from crystals grown on Roadrunner I chips. The Ca2+-binding site of proteinase K and the active site of thermolysin with two bound Zn2+ ions (gray spheres) are shown. Residues that are involved in ion binding and/or are functionally important are represented as sticks and labeled. For a more detailed discussion on the thermolysin structure, please see the supporting information.
