Figure 2 (a) Stereo plot illustrating the anomalous difference
map (red) contoured at 4.5 surrounding
the buried chloride (green) in the interior of the protein and
the S atoms (yellow). Magnesium is displayed as an orange
sphere. (b) Stereo plot of the interactions between the chloride
ion (green sphere) and the protein main-chain N atoms of Tyr43,
Cys44, Ile123 and the O^ atom
of Ser41. Two disulfide bridges in the vicinity of the
chloride-binding site are also displayed. This figure was
prepared with PyMOL (DeLano, 2002[DeLano, W. L. (2002). The
PyMOL Molecular Visualization System. http://www.pymol.org .])
and MOLSCRIPT (Kraulis, 1991[Kraulis, P. J. (1991). J. Appl.
Cryst. 24, 946-950.]).
