Figure 1 Structures of PARNn in free and RNA-bound forms. (A)
Stereo diagram of 2.6 Å simulated annealing (SA) omit map
contoured at 2 covering
the bound poly(A) in the PARNn-RNA complex. The last three
nucleotides are shown in stick model. (B) A ribbon diagram of
the PARNn-RNA complex. The two molecules are shown in yellow and
green, respectively. Nucleotides are shown in stick model. 3,
4
and 5
are labeled in (B, C). (C) Superimposition of the PARNn-RNA
complex with native PARNn. The color coding for the PARNn-RNA
complex is as in (B). The two molecules (chain A and chain B) of
native PARNn are highlighted with dark green and orange,
respectively. Nucleotides are shown in stick model.
