Receptor Recognition Mechanism of Coronaviruses part 4

  Coronaviruses belong to the Coronaviridae family in the order of Nidovirales. They can be classified into at least three major genera, α, β, γ (formerly group 1, 2, and 3, respectively).

Receptor Recognition Mechanism of Coronaviruses part 3

  Coronaviruses are a group of common, ancient, and diverse viruses. They infect many mammalian and avian species and cause respiratory, gastrointestinal and central nervous system diseases. Coronavirus virions contain an envelope, a helical capsid, and single-stranded and positive-sense RNA … Continue reading

Receptor Recognition Mechanism of Coronaviruses part 2

  The receptor-binding S1 subunit of coronavirus spike proteins contain two distinctive domains, the N-terminal domain (S1-NTD) and the C-terminal domain (S1-CTD), both of which can function as receptor-binding domains (RBDs). S1-NTDs and S1-CTDs from three major coronavirus genera recognize … Continue reading
