Figure 3. Surface Charge Distribution of Opposite Faces of
X29
Blue indicates regions of positive surface charge and
red indicates negative, contoured at ± 5kt cutoff, respectively.
Overlaid ribbon in (C) shows extensions (black arrow pointers)
that define the two sides of the inferred RNA binding channel,
which is indicated by yellow arrows. Active sites of each
monomer are occupied by m7GpppA (gold and green ball-and-stick).
Views are down the dyad axis.
