A: ‘Bound state’ of F486 in the distance of 5–7 Å (measured between F486‐Cz atom and Cb‐atom of Y82); B: ‘Fixed state’ of F486 outside the binding pocket; C: ‘Deformed state’ of Bp C. The numbering of residues refers to the canine sequence. Colour‐code: grey backbone – canine ACE2, green backbone – SARS‐CoV‐2, orange line – the measured distance between F486Cz and Y82Cb, grey surface – the molecular surface of canine ACE2 residues (V24, F27, L78, T81 and Y82).
