Figure 2. Structures in the vicinity of the residue 56 in
the wild-type (a) and I56A (b) to (d), and those of the residue
59 in the wild-type (e) and I59A (f). In (c) and (d), dummy
water molecules, which were estimated to be energetically
favorable using the program, X-PLOR [Brunger 1992], are drawn.
The dummy water molecules in (c) and (d) made hydrogen bonds
with O^γ of Ser36 and an internal water molecule, respectively.
The side-chain atoms of the residues 56 and 59, carbon atoms,
oxygen and nitrogen atoms, interior water molecules, introduced
water molecules and the dummy water molecules are represented by
green, yellow, orange, blue, dark blue and purple, respectively.
