Comparison of the crystal structures of the wild-type and S586N-mutated HeV-G proteins. a, b Overlay of the crystal structures of wild-type (cyan) and mutant (orange) HeV-G. The red dotted line at higher magnification shows the measured distance between wild-type Ser 586 and substituted Asn 586 on the mutant. Comparison of the electrostatic surface potential on wild-type (c) and S586N-mutated HeV-G (d) proteins. The distinctive areas are indicated by black lines
