Figure 5. The glycine-bridge region. (a) Section of the
deoxy-rHb 1.1 electron-density map showing the glycine-bridge
region of the di-a-chain. (b) Section of the cyanomet-rHb 1.1
electron-density map showing the glycine bridge region of the
di-a-chain. Residues Arga141, Glya142, and Vala143 are shown.
The maps are contoured at 0.75s using coefficients (2F[o] -F[c])
and phases from the final models. The atoms are colored by atom
type (yellow, carbon; red, oxygen; blue, nitrogen).
