Figure 5.
Figure 5. The structure of the Exo84p C terminus is similar to
that of the Exo70p N terminus. (a) Exo84p C-terminal fragment
(residues 523-753), colored from blue at residue 523 to red at
residue 753. (b)Exo84 C-terminal fragment colored according to
electrostatic surface potential (on a scale from -13 kT to +11
kT), where blue is positive and red is negative. The view on the
left is as in a. (c) Exo70p N-terminal fragment (residues
67-341). (d) A superposition of the Exo84p C terminus (blue) and
the Exo70p N terminus (pink) aligned using helices H1-H4 of
Exo84p and H1-H3 and H5 of Exo70p (circled). The two helical
bundles comprising the two protein fragments are differently
oriented in Exo84p and Exo70p. The view is as in a and c. (e) A
superposition of the Exo84p C terminus and the Exo70p N terminus
aligned using helices H5-H9 of Exo84p and H6-H10 of Exo70p
(circled). In the interest of clarity, the view is rotated with
respect to that in d. Lsqman34 was used in the alignments in d
and e. Figures were prepared with MolScript32 and GRASP33.
