Unresolvable Taxon:10699 (taxid:10699)

VIRION

Non-enveloped, head-tail structure. The head is about 60 nm in diameter. The long tail is non-contractile and has 6 fibers although some siphoviruses have only 3 or 4. The capsid is icosahedral with a T=7 symmetry.

GENOME

Linear, dsDNA genome of about 50 kb, containing about 70 genes.

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.
