Overview of the solution structure of ScPcf11 538–608. (A) Superposition of the 20 lowest-energy structures on the left and the representative lowest energy structure, shown in ribbon on the right. Secondary structure elements are labeled and the side chains of zinc coordinating residues are drawn in sticks. (B) Same as A but rotated by 90° around the indicated axis. (C) Close-up view of the zinc-binding site. The distances between the zinc ion and its coordinating atoms are indicated in red (Å).
