Phijl1virus

VIRION

Non-enveloped, head-tail structure. The icosahedral head is about 59 nm in diameter. The non-contractile tail is about 182 nm in length and 11 nm wide. There is a baseplate with spikes or fibers.

GENOME

Linear dsDNA genome of 37 kb, containing about 46 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.
