Timquatrovirus (taxid:1623306)



Non-enveloped, head-tail structure. The icosahedral head is about 60 nm in diameter. The non-contractile tail is about 600 nm in length.


Linear dsDNA genome of 52-62 kb, containing about 94-98 genes.




  1. Adsorption: The phage attaches to target cell adhesion receptors through its tail fibers.
  2. Ejection of the viral DNA into host cell cytoplasm by long flexible tail ejection system.
  3. Transcription and translation of early genes.
  4. Replication of genomic DNA.
  5. Transcription and translation of late genes
  6. Assembly of an empty procapsid and packaging of the genome.
  7. Viral tail fiber assembly and viral tail assembly.
  8. Mature virions are released from the cell by lysis.
