Kuravirus

VIRION


image

Non-enveloped, head-tail structure. The prolate head is about 145 nm x 44 nm and the tail 13 nm x 8 nm, with short, possibly kinked tail fibers folded on the tail.

GENOME

Linear, dsDNA genome of about 77 kb encoding for 128 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.
