Tequatrovirus (taxid:10663)
VIRION
|
Non-enveloped, head-tail structure. The prolate head is 120 nm in length and 86 nm in width. The tail is contractile, has 6 long terminal fibers, 6 short spikes and a small base plate. The capsid has an elongated icosahedral symmetry T=13 Q=21, composed of 152 capsomers .
GENOME
Linear, dsDNA genome of about 169 kb, encoding for approximately 300 proteins.
GENE EXPRESSION
Genes are transcribed by operons.
REPLICATION
CYTOPLASMIC
- Adsorption: the phage attaches to the target cell through its tail fibers.
- Viral exolysin degrades cell wall locally
- Ejection of the viral DNA into host cell cytoplasm by contraction of the tail sheath.
- Transcription and translation of early genes.
- Replication of genomic DNA. Transcription and translation of late genes.
- Assembly of an empty procapsid and packaging of the genome.
- Viral tail fibers assembly and viral tail assembly.
- Mature virions are released from the cell by lysis.
