Comparison of subdomains in the RdRp region. For overall structure comparison, parts of structures of RVFV L protein, SFTSV L protein (PDB 6L42), LACV L protein (PDB 5AMR), and Influenza A polymerases (PDB 4WSB) were shown side by side. Regions corresponding to influenza virus PA-like region (A), PB1-like region (B), PB2-like region (C), and overall architectures (D). Colors correspond to Fig. 3A
