Figure 3. The hydrophobic region
of the S100P monomer. (a) A ball-
and-stick representation of the
hydrophobic core formed by F71,
F74, and F15, hydrogen bonds
between two b-strands by L28 and
V69 are coloured in blue. Phenyl-
alanine residues are shown in
yellow, and other hydrophobic
residues labelled are shown in the
same colour as their helices (see
Figure 2). The monomer is coloured
as in Figure 2. (b) Ribbon and atom
sphere surface representations of
the hydrophobic globe. The hydro-
phobic core is further enlarged to a
globe by many hydrophobic
residues in khaki. The monomer is
coloured in slate-blue, and calcium
ions are shown in blue. The atom
sphere surface was drawn by the
program GRASP.
