Bcep22likevirus

VIRION



Non-enveloped, head-tail structure. The capsid is about 71 nm in diameter. The short tail is non-contractile and measures 15 nm in length by 14 nm in width. Presence of a single tRNA.

GENOME

Linear, dsDNA genome of about 62-64 kb encoding for 77 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.
