Figure 2. The two monomers of FluA in the asymmetric crystal
unit. Each polypeptide chain is shown in a ribbon presentation,
light- and dark-gray, respectively, with its N- and C-terminus
labeled and the fluorescein ligand depicted as a ball-and-stick
model. The intermolecular -sheet
that is formed via association of the loop #3 segments from the
two monomers can be seen at the middle, together with the
position of the crystallographically fixed sulfate ion.
