Figure 8
The overlaid catalytic center of VP55 in the VP55 monomer and the VP39-VP55 heterodimer based on a superposition of the central domain (residues 161-278). The residues (as well as 3'-dATP and the RNA primer) from the 3'-dATP/RNA-bound heterodimer (PDB entry 3erc , chain C) are colored gray, while those from chain B in the VP55 monomer are green. The 2Fo - Fc OMIT map for the VP55 monomer is shown at the 1[sigma] contour level. Residues discussed in the text are labeled.  [article HTML]
