VIRION
Non-enveloped, head-tail structure with Sipho-type morphology. The icosahedral head is about 54 nm in diameter. The non-contractile tail is about 131 nm in length.
GENOME
Circular, dsDNA genome of about 55 kb, containing about 105 genes.
GENE EXPRESSION
ENZYMES
- Integrase [Int]
REPLICATION
CYTOPLASMIC
- The phage attaches to the target cell adhesion receptor FhuA through its tail fibers.
- Ejection of the viral DNA into host cell cytoplasm by long flexible tail ejection system.
- Transcription and translation of early genes.
- Replication of genomic DNA, formation of viral genome concatemers.
- Transcription and translation of late genes
- Assembly of an empty procapsid and packaging of the genome through a headful mechanism.
- Viral tail fibers assembly and viral tail assembly.
- Mature virions are released from the cell by lysis.
