D3virus

VIRION

Non-enveloped, head-tail structure. The icosahedral head is about 55 nm in diameter. The major capsid subunit proteins are cross-linked creating oligomers. The non-contractile tail is about 113 nm in length and 7 nm in width, possessing six tail fibers with terminal knobs.

GENOME

Linear, dsDNA genome of about 98 kb, encoding about 98 proteins. Displays 3’ cohesive ends (Pseudomonas phage D3).

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.
