Figure 5.
FIGURE 5. The native TSPN-1 structure in P1 space group. A,
a ribbon drawing of the two TSPN-1 domains in one asymmetric
unit. They are not related by any pseudo-symmetric operation.
Residue Arg-42 from the major heparin-binding site of each
domain is drawn in ball-and-stick form. The two TSPN-1 domains
interact with each other extensively through their edge strands
(see "Results"). The electric dipole moment of the two TSPN-1
domains is shown by the blue arrow and centered at the beginning
of the arrow. B, an electrostatic potential surface
representation of the two TSPN-1 domains in the native TSPN-1
structure. Residue Arg-42 from the major heparin-binding site of
each TSPN-1 domain is labeled to show the separation of the two
major heparin-binding sites in this native structure. The
orientation of the figure is similar to the one shown in panel A.
