YfeA model fit. (a) Apo YfeA. The model, colored by B factor, is overlaid with anomalous difference electron density contoured at 5σ (magenta mesh) and electron density calculated from a 2Fo − Fc map contoured at 1σ (blue mesh). Missing or broken electron density is apparent for helix 7. (b) Reconstituted holo YfeA. The model, colored by B factor, is overlaid with anomalous difference electron density contoured at 5σ (magenta mesh) and electron density calculated from a 2Fo − Fc map contoured at 1σ (blue mesh). Contiguous electron density is apparent for helix 7. |
