Extended Data Fig. 2: Structural comparison of sNSV L Endonucleases.

Endonuclease region of TSWV L (a), LACV L (b), SFTSV L (c), LASV L (d) and FluA polymerase (e): schematic representation (top) and structure (bottom). Corresponding structural elements are presented in the same color. The side chains of the key motif that constitute the active site are displayed as orange sticks. f, N-lobe of TSWV endo and an iron binding protein (PDB ID: 6N63) exhibit a remarkably high degree of structural similarity.
