Figure 1. Crystal structure of the
tailspike protein lacking the head-
binding domain complexed with
O-antigen octasaccharide. Stereo
diagrams of a side view (top) and
a cross-section through the b-
helices of the trimer (bottom) are
depicted. The binding site is shown
with octasaccharide only in one
subunit, for which only the C
a
-
trace is drawn. The other two
subunits are shown in an all atom
presentation. Note the solvent-
exposed groove in which the
saccharide is bound.
