Figure 5 Least-squares fit of C chains
of the ten subunits of the decamer, plus the three structures
4PTI, 5PTI and 6PTI crystallized in phosphate. The locations of
the binding zones of thiocyanates are indicated by dashed
circles with respect to this common target molecule. The two
phosphate anions of 5PTI and 6PTI structures are also reported -
they correspond to the anionic site 1. Due to
non-crystallographic symmetry considerations, the three anionic
sites correspond to four different binding zones. Site 1 and
site 1' are equivalent within each pentamer (molecules
SCN1-SCN3) e.g. thiocyanate-labelled SCN1 lies in site 1 for
subunit G and in site 1' for subunit F. Site 3 (SCN4-SCN7) is in
the vicinity of residues 47-49 of dimers A/F, B/J, C/I and E/G,
while site 4 (SCN8-SCN10) connects pairs of Lys46 from two
different pentamers: D/I, B/F and H/E.
