Figure 2.
Figure 2 Electron-density map of the -chain heme pocket of the 2 resolution of COHbC showing the high quality of the electron-density map, as exemplified by the proximal and distal histidines, and the heme group and CO molecule. Stereoview of 2F[o] - F[c] electron-density contour map built around the heme, His58 and His87 of the -subunit of COHbC.
