Sp6virus

VIRION


Non-enveloped, head-tail structure. Head is about 60-65 nm in diameter. The tail is non-contractile, has 6 prominent tail spikes.

GENOME

Linear, dsDNA genome of about 43 kb encoding for 52 genes.

GENE EXPRESSION

REPLICATION

CYTOPLASMIC

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