Spherical shape of coronavirus is characterized by heavily glycosylated spike (S), matrix or membrane (M) and envelope (E) proteins on the surface, and helical nucleocapsid inside which is formed by binding of the nucleocapsid (N) proteins on the genomic RNA. Receptors: ACE2 (angiotensin converting enzyme) and TMPRSS2 (Transmembrane protease, serine 2)
