Che9cvirus

VIRION

Non-enveloped, head-tail structure. The prolate head is about 700nm in length and 250 nm in width. The non-contractile tail is about 1000 nm in length with a baseplate.

GENOME

Linear dsDNA genome of 47-57 kb, containing about 84 genes.

GENE EXPRESSION

REPLICATION

CYTOPLASMIC

  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.
