Figure 3. Superposition of backbone traces of the energy
minimized average structure derived from NMR (shown in cyan) and
the X-ray structure (shown in red) around Gly 295. The
structures were superimposed to give the lowest deviations in
the C^α positions of residues 270 to 322. The largest deviation
occurs at Gly295. Side-chains which might be involved in
electrostatic interactions with the adjacent molecule (green) in
the crystal (distance between N and O atoms is less than 4
Å) are shown in white. Plausible hydrogen bonds or salt
bridges are indicated by broken lines, with distances in
angstroms. The crystal structure is that of [Story et al 1992].
This Figure was drawn using MidasPlus [Ferrin et al 1988].
