FIGURE 5. Crystal structure of trimeric NCRD bound to
maltotriose. Ribbon representation of protein viewed
perpendicular to axis of neck domain, each subunit colored
differently. Maltotriose is shown as a ball-and-stick model and
calcium ions as green spheres. Maltotriose is bound in the same
orientation in each subunit. However, the interaction of the
trisaccharide with calcium ion 1 and the binding surface is most
clearly shown in the cyan subunit at left.
