Non-enveloped, head-tail structure. The icosahedral head is about 96 nm in diameter. Has a neck without a collar, and a small base plate. The tail of about 97 nm in length and 21 nm in width is contractile. There is a baseplate with a bundle of presumably six tail fibers about 38 nm in length.
Circularly permuted dsDNA genome of about 132 kb, encoding for about 149 proteins.
Genes are transcribed by operons.
- Adsorption: the phage attaches to the target cell through its tail fibers.
- Ejection of the viral DNA into host cell cytoplasm by contraction of the tail sheath.
- Transcription and translation of early genes.
- Replication of the viral genome. 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.
