Figure 5.

(A) Radial and (B) axial views of HiDapE’s binding pocket with succinate acid and l,l-DAP bound in the closed conformation, generated from the crystal structure (PDB entry) utilizing the PBTSM protocol. Succinate and l,l-DAP are colored cyan and yellow, respectively, while protein chains A and B are colored dark green and orange, respectively. The Zn(II) ions are shown as black spheres and waters as red spheres; amino groups are colored dark blue and red for nitrogen and oxygen, respectively.
