Tequintavirus

VIRION

Non-enveloped, head-tail structure. The capsid is about 90 nm in diameter, with a T=13 icosahedral symmetry . It is composed of 11 pentamers at the vertices and 120 hexamers on the faces. The tail is about 160 nm in length and 9 nm in width, with a subterminal disk and 3 long kinked fibers (120 nm). There is also a conical tip with a single straight central fiber (50 nm).

GENOME

Linear, dsDNA genome of about 121 kb, containing about 160 genes.

GENE EXPRESSION

REPLICATION

CYTOPLASMIC

  1. Adsorption: The phage attaches to target cell adhesion receptors through its tail fibers.
  2. Viral exolysin degrades host cell wall locally.
  3. Ejection by long flexible tail ejection system: viral DNA is injected in host cell cytoplasm.
  4. Transcription and translation of early genes.
  5. Replication of genomic DNA by DNA strand displacement replication.
  6. Transcription and translation of late genes
  7. Assembly of an empty procapsid and packaging of the genome.
  8. Viral tail fibers assembly and viral tail assembly.
  9. Mature virions are released from the cell by lysis.
