Human coronavirus OC43

Human coronavirus OC43[1] (HCoV-OC43) is a member of the species Betacoronavirus 1, which infects humans and cattle.[2][3] The infecting coronavirus is an enveloped, positive-sense, single-stranded RNA virus that enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid receptor.[4] OC43 is one of seven coronaviruses known to infect humans. It is one of the viruses responsible for the common cold[5][6] and may have been responsible for the 1889–1890 pandemic.[7] It has, like other coronaviruses from genus Betacoronavirus, subgenus Embecovirus, an additional shorter spike protein called hemagglutinin-esterase (HE).[8][2]

PMID 27578435. BCoV S1-NTD does not recognize galactose as galectins do. Instead, it recognizes 5-N-acetyl-9-O-acetylneuraminic acid (Neu5,9Ac2) (30, 43). The same sugar receptor is also recognized by human coronavirus OC43 (43, 99). OC43 and BCoV are closely related genetically, and OC43 might have resulted from zoonotic spillover of BCoV (100, 101).

In all members of Betacoronavirus subgroup A, a haemagglutinin esterase (HE) gene, which encodes a glycoprotein with neuraminate O-acetyl-esterase activity and the active site FGDS, is present downstream to ORF1ab and upstream to S gene (Figure 1).
