Figure 4. Improvement of the Structural Model of KcsA in Normal-Mode Refinement.

Figure 4

(A–C) The top panels show the original model superimposed with the 2Fo – Fc map. (A′–C′) The bottom panels show the refined model superimposed with the 2Fo – Fc map calculated with the added side chains omitted. (A and A′) Residue Ile60 with the 2Fo – Fc map contoured at 1.0σ. (B and B′) Residue Glu71 with the 2Fo – Fc map contoured at 1.0σ. (C and C′) Residue Arg117 with the 2Fo – Fc map contoured at 2.0σ.
