Betakoronavirus 1

Betakoronavirus 1 je vrsta koronavirusa koja inficira ljude i stoku. Virus koji inficira je jednolančani RNK virus, s pozitivnim osjećajem, i pripadnik je roda Betakoronavirus i subgena Embecovirus.^[1] Kao i ostali embekovirusi ima dodatni kraći površinski protein u obliku šiljka, nazvan hemaglutinin esteraza (HE).^[2]^[3]

ISSN 1999-4915. PMC 3185738. PMID 21994708. 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).

ISSN 1999-4915. PMC 3185738. PMID 21994708. 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.
