Figure 3. Overall Structure of Aa-E110KˇdsRNA(A)
Illustration of a biological dimer of the Aa-E110KˇdsRNA
complex. The crystallographically independent molecule and its
symmetry mate are indicated by N-C, and N'-C', respectively.
Secondary structural elements are labeled for those in dsRBD and
a3 in the endoND. The endoND, dsRBD, dsRNA, endoND^sym,
dsRBD^sym, and dsRNA^sym are colored yellow, green, green, cyan,
blue, and blue, respectively. The RNase III signature motif at
the N terminus of a3 is highlighted in red. Helices, b strands
and loops are drawn as spirals, arrows, and pipes,
respectively.(B) A different view of dimeric Aa-E110KˇdsRNA
related to the view in (A) by a 90° rotation around the vertical
axis.
