Figure 2. Structure of an nsNSV polymerase.
(A) Linear representation of the VSV L protein, indicating the positions of conserved regions I-VI relative to the different domains. (B) Views of the VSV L protein structure (PDB 5a22) (8). The domains identified by Liang et al are as follows: RdRP (blue), capping (green), connector domain (yellow), methyltransferase domain (orange) and C-terminal domain (red).
