Oshimavirus

VIRION

image


Non-enveloped, head-tail structure. The icosahedral head is about 100 nm in diameter, and has a T=7 icosahedral symmetry . The non-contractile tail is about 1000 nm in length.

GENOME

Linear dsDNA genome of about 84 kb, containing about 117 genes. The genome contains long polypurine-polypyrimidine (R-Y) sequences with mirror repeat symmetry.

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.
