FIG. 3. The saccharides of AaV-SP-I and -II. A and B, the
electron density (2Fo-Fc) maps of NAG301-FUC^302-NAG303 and
NAG301 of AaV-SP-I and AaV-SP-II are contoured at the 1.0 level.
C, superimposed C atoms of segments
formed by residues 30-70 for comparing the saccharide residues
between AaV-SP-I (cyan) and -II (yellow). The His57 and the
Asp59 of AaV-SP-I as well as saccharides of the two AaV-SPs are
shown with a stick model. The two hydrogen bonds in AaV-SP-I,
one between FUC^302 and His57 and the other between FUC^302 and
Asp59, are labeled.
