Figure 5
Electron density maps of the last data set measured at 8.3 keV (a1, b1), 12.4 keV (a2, b2) and 33.0 keV (a3, b3). Carbon, oxygen, nitrogen and sulfur atoms are colored yellow, red, blue and green, respectively. Both 2Fo − Fc maps contoured at 1.0σ (green) and Fo − Fc maps contoured at 3.0σ (blue) or −3.0σ (red) are superimposed on two disulfide bonds formed by Cys76 and Cys94 (a1, a2, a3) or formed by Cys6 and Cys127 (b1, b2, b3), respectively. These figures were drawn using CueMol (https://www.cuemol.org
