Figure 2.
Figure 2 Stereo view of putative binding site and cavities. The
cavities as calculated by GRASP (Nicholls et al., 1991) are
shown in different colors. Cavities shown in blue and green are
at the top of the molecule away from the membrane surface.
Residues forming these cavities are shown as a stick model in
corresponding colors. Each cavity has a volume of 50 Å3 and is
formed by residues Ala75, Ile76, Gly77, Lys78, Lys79, Glu89,
Ala90, Asp91, His92 and Asn93 of one monomer, and Gly94, Ser95,
Ser98, Gly146, Lys147 and Glu148 of the other monomer. The
solvent structures in the cavities are remarkably well conserved
between the HB19 and B31 molecules.
