Figure 4.
Figure 4. Representation of the solution structure of the
SBD. The N and C termini and b-strand numbers are
marked. The strands are shown as arrows which also
indicate their directionality. The atomic coordinates of
SBDav-min were used and the molecule was oriented by eye
to give the best view of the b-strands. The orientation is
rotated by approximately 180° about the vertical axis
compared to Figure 3. The Figure was generated using
the program MOLSCRIPT (Kraulis, 1991). The position of
the disulphide bond is highlighted by ball figures for S
g
atoms and lines for C

(interresidue) bonds for residues 509 and 604.
