Figure 6.
Figure 6. Space-filling representation of the hydrophobic
core (a) and a stick diagram of salt-bridges (b) at the dimeric
interface of the Ste11 SAM domain. The helices are represented
by ribbons. (c) Stick diagram of the dimeric structure of the
Ste11 SAM domain showing surface-exposed hydrophobic residues.
(d) Electrostatic potential surface of the Ste11 SAM dimer. The
asymmetric charge distribution of the dimer of each face is
shown. Colored in red is negatively charged, blue positively
charged and white neutral. This Figure was made with the GRASP
program.54
