Embecovirus
Embecovirus is a subgenus of coronaviruses in the genus Betacoronavirus. The viruses in this subgenus, unlike other coronaviruses, have a hemagglutinin esterase gene. The viruses in the subgenus were previously known as group 2a coronaviruses.Structure
The viruses of this subgenus, like other coronaviruses, have a lipid bilayer envelope in which the membrane, envelope and spike structural proteins are anchored. Unlike other coronaviruses, viruses in this subgenus also have an additional shorter spike-like structural protein called hemagglutinin esterase.Recombination
can occur when two or more viral genomes are present in the same host cell. The dromedary camel beta-coronavirus exhibits genetic diversity in the African camel population. Contributing to this diversity are several recombination events that had taken place in the past between closely related Beta-CoVs of the subgenus Embecovirus.
