Comparisons of the VSV and FLUAV N structures. Stereo cartoon drawings for the superposition of the C-terminal domain of the FLUAV N protein (yellow) with that of the VSV N protein (blue), and the superposition of the N-terminal domain of the FLUAV N protein (dark green) with that of the VSV N protein (blue). The two domains in the FLUAV N protein were aligned with their counterparts in the VSV N proteins as separate domains. In the case of the N-terminal domain, only the core residues 56–147 were included in the calculation for structural alignment by FATCAT. Residue positions of the aligned structures are shown in the box below each structural comparison. '1' marks the aligned residues between the two structures. Cartoon drawings are also presented on the right with α-helices in VSV N labeled. Statistics for the domain alignments could be found in Table 1B and 1C.
