FIG. 5. a, Fourier difference map (F[o] - F[c]) at 3 with the pyruvate residue omitted from the refinement of the native drNimA structure. The finally refined pyruvate is given along with some surrounding residues. b, a LIGPLOT (41) presentation of the chemical environments of the pyruvate in the final drNimA structure, with inter-atomic distances for polar interactions.
