Figure EV3. Sequence alignment of N proteins from seven human‐infecting coronaviruses.

The secondary structure elements α‐helix, β‐sheet and turn are shown as spirals (α‐helix), arrows (β‐strand) and “TT” letters (turn), respectively. The residue numbers of each sequence are labelled on the left of the alignment, and black dots above the sequence alignment mark the residue number according to SARS‐CoV‐2 N at intervals of 10. Identical residues are highlighted in red background, and similar residues are labelled in red and boxed in blue lines.
