Figure 3 (A) Superposition of all seven blades of Tup1. The C[
]backbone
for each of the seven blades was aligned with respect to strands
3B and 3C. The four conserved side chains involved in the
intrablade hydrogen-bonding network, referred to as the
structural tetrad, are shown for blade 3 as ball-and-stick
models colored according to atom type and hydrogen bonds are
indicated with dashed lines. A representative blade from G ,
blade 4, is shown for reference. Blade 1, light green; blade 2,
red; blade 3, green; blade 4, purple; blade 5, pink; blade 6,
cyan; blade 7, orange; G ,
brown. (B) Superposition of the WD40 propellers. The C[ ]backbones
for G (blue;
1TBG) and Tup1 (yellow), which align with an r.m.s.d. of 1.3
Å, are shown in the same view as Figure 1A and labeled.
Least-squares alignments for (A) and (B) were done in O (Jones
et al., 1991) and figures generated with RIBBONS (Carson, 1997).
