Figure 3. Stereo View of the RNA Triphosphatase MonomerA
stereo image of the Cα trace of the Cet1(241–539)p monomer
was prepared with the program SETOR ([7]). The view is looking
into the tunnel entrance (as in Figure 4A). An enzyme-bound
sulfate coordinated within the tunnel is shown as a stick model.
Basic amino acid side chains that point into the tunnel are
shown in blue. Acidic side chains that point into the tunnel are
shown in red.
