Aggregaviridae (taxid:2946155)

VIRION

image

Non-enveloped, head-tail structure with Myo-type morphology. The icosahedral head is about 43 nm in diameter. The contracted tail is between 123 nm in length with a myoviral morphology.

GENOME

Circular, dsDNA genome of about 43 kb, encoding for about 79 proteins.

GENE EXPRESSION

Genes are transcribed by operons.

ENZYMES

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 by contraction of the tail sheath.
  3. Transcription and translation of early genes.
  4. Replication of the viral genome. 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.
