Figure 7. Substitutions that may inhibit polymerase rearrangement.
The VSV L protein with RdRP, capping and methyltransferase domains is shown. The RdRp is in pale blue with the active site (viewed through the template entry channel) and putative priming loop colored gold. The capping domain is colored green and the methyltransferase in orange. Residues corresponding to substitutions that inhibit both transcription and replication in Sendai virus, that are distant from the RdRp active site are shown in magenta.
