Figure 1 (A) Ribbon diagram of the bovine PAP complex with
3'-dATP. The catalytic domain (residues 60–173) is shown in
orange, the central domain in blue (residues 20–59 and
174–352) and the C-terminal RNA-binding domain in purple
(residues 353–498). The 3'-dATP molecule bound in the active
site is shown in magenta, and the three metals ions are shown as
yellow spheres. Helices are designated with letters, -strands
with numbers. (B) Stereo view of the PAP complex in the same
orientation as in (A). Every 20 residues are labeled. Secondary
structure elements were determined by Procheck (Laskowski et
al., 1993). Figures 1, 3, 4 and 5 were generated with SETOR
(Evans, 1993).
