Figure 8
Dose-dependent nitrate reduction observed in the `nitrate II4'-soaked crystal in the vicinity of the Cys6—Cys127 bond [panels (a)–(f) correspond to datasets d1–d6, respectively]. The 2Fo − Fc map (blue) is contoured at σ = 1.2 and the Fo − Fc map is contoured at σ = ±3.0 (green: +; red: −). The reduction of the nitrate molecules correlates with the appearance of density in the difference map of Fig. 5c(IV). |
