Figure 2. (a) Structure of the Impa(70-529)-SV40 NLS
complex. Importin-a is shown as a ribbon diagram (lavender;
drawn with program RIBBONS [Carson 1997]). The superhelical axis
of the repetitive part of the molecule is approximately
horizontal. The two SV40 NLS peptides are shown in a
ball-and-stick representation; the peptide bound to the major
site is colored yellow, and the peptide bound to the minor site
is colored orange. (b) Structure of Impa(70-529)-nucleoplasmin
NLS complex, shown as in (a). The nucleoplasmin NLS peptide is
colored cyan.
