Ramachandran Plots Showing Differences in Phi and Psi Angles before and after Nitrate Binding
(A) Protomer A nitrate unbounded; (B) protomer A nitrate bounded. In (A) and (B), H356 and T360 are the ligand-binding pocket residues and T101 is the phosphorylation site. (C) Protomer B nitrate unbounded; (D) protomer B nitrate bounded. In (C) and (D), H356 and R45 are the binding pocket residues.
