Figure 4.
FIGURE 4. The side chain of Arg^222 (NH1) at the C-terminal
domain interacts with Asp^151 (OD2) of the N-terminal domain
through a salt bridge. The N-terminal domain is shown in yellow,
C-terminal domain in cyan, and interdomain coil in gray. Asp^151
and Arg^222 are represented in stick model (carbon atoms are
colored the same as the domain they locate at) and the metal ion
by a sphere (gray). Salt bridge is shown by dashed line. The
figure was created by PyMol.
