Figure 3.
Fig. 3. A stereo view of the unique self-stacking
arrangement of the porphyrin molecules in the
H[2]TPPS·ConA complex. The stacked porphyrins are
slightly staggered to prevent steric clashes between the side
groups (thick blue sticks). Two stacked porphyrins are
surrounded by four independent monomers of ConA. The porphyrin
in the asymmetric unit interacts with only six amino acid
residues of ConA. The ConA residues (sticks) and water molecules
(spheres) of one asymmetric unit involved in interactions with
porphyrin are shown in the same color.
