Fig. 2. Ribbon and surface representations of CBM6. a,
view showing the ligand-binding cleft (cleft A) formed by the
loops between the two -sheets of
the sandwich fold. b, surface representation of CBM6 in the same
orientation as in a. The shallow binding cleft on top of the
globular molecule is formed by Tyr-34 and Trp-92. c, ribbon
representation of CBM6 in a perpendicular view with respect to
a, showing the second possible cleft (cleft B), which is
obstructed by a short loop in CBM6, situated on the concave face
of the -sheet
sandwich. a and c were produced with Molscript (45) and Raster3D
(46), whereas b was produced using GRASP (47).
