Figure 7. Superposition of the apo and RA-bound forms of PrTX-I.

Figure 7

(a) Ribbon representation of both homodimer structures. (b) superposition between corresponding protomers of the structure. The r.m.s.d. values for the whole protomer chain superposition and for the C-terminal region (residues 115–129) are shown. The higher r.m.s.d. for protomer B is due to allosteric changes induced by the ligand in the C-terminal region.
