Figure 8.
FIGURE 8. The BAF[2]-Em^LEM interface. A, ribbon diagram of
the BAF[2]-Em^LEM complex (color coded as in Fig. 7A) also
illustrating the position of the two DNA duplexes observed in
the crystal structure of the BAF[2]-DNA[2] complex (5). B,
surface representations illustrating the binding surfaces
involved in the BAF[2]-Em^LEM complex. The binding surface on
BAF[2] is shown on the left panel and on Em^LEM on the right
panel. The binding surfaces are color coded with hydrophobic
residues in green, polar residues in light blue, positively
charged residues in dark blue, and negatively charged residues
in red. The relevant portions of the interacting partner are
shown as gold tubes. The surface of the non-interacting residues
of the BAF[2] dimer is shown in dark gray for the red subunit
and light gray for the blue subunit (as depicted in A). Residues
of the blue subunit of BAF[2] are labeled in lowercase, and
residues of Em^LEM in italics. The view in the right-hand panel
is related to that in the left-hand panel by a 180° rotation
about an axis parallel to the printed lines on the page.
