Figure 4. The structure of RBD2. (a) Superposition of the
main-chains of 20 refined structures. N and C indicate K110 and
A184, respectively, and loop 3 is labeled. (b) Schematic drawing
of the restrained energy minimized mean structure derived from
the 20 refined structures, as viewed from the same direction as
that in (a). (c) Hydrophobic core. Overlaying of the 20
structures of the side-chains for residues involved in the
hydrophobic core is shown on the main-chain of the restrained
energy minimized mean structure. α-Helices and β-strands are
colored red and sky-blue, respectively. (d) Hydrophobic patch
exposed to the solvent. The same overlaying as that in (c) is
shown for F112, F152 and F154, being rotated by ca 90 ° from
that in (c).
