Betacoronavirus 1 is a species of coronavirus which infects humans and cattle.[4][5] The infecting virus is an enveloped, positive-sense, single-stranded RNA virus and is a member of the genus Betacoronavirus and subgenus Embecovirus.[6] Like other embecoviruses, it has an additional shorter spike-like surface protein called hemagglutinin esterase (HE) as well as the larger coronavirus spike protein.[7][8]

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).

The presence of HE genes exclusively in members of Betacoronavirus subgroup A, but not members of Betacoronavirus subgroup B, C and D suggested that the recombination had probably occurred in the ancestor of members of Betacoronavirus subgroup A, after diverging from the ancestor of other subgroups of Betacoronavirus.
