Yingchengvirus is a genus of double stranded DNA viruses that infect haloarchaea.[1] The genus was previously named Betasphaerolipovirus .[2]
Taxonomy
[ edit ]
The genus contains the following species:[3]
Morphology
[ edit ]
Viruses of this genus have tailless icosahedral virions with an internal lipid membrane located between the protein capsid and the circular double stranded DNA genome.
Replication
[ edit ]
The temperate haloarchaeal virus SNJ1 displays lytic and lysogenic life cycles. During the lysogenic cycle, the virus resides in its host in the form of an extrachromosomal circular plasmid . Upon mitomycin C induction , large amounts of SNJ1 virions can be produced.[4] SNJ1 genome replicates by the rolling-circle mechanism and is initiated by the virus-encoded RepA protein, which is homologous to the replication-initiation proteins of archaeal plasmids and bacterial transposases of the IS91 family insertion sequences .[5] [6] The virus is released by lysis of the infected cells.
