VIRION
Non-enveloped, head-tail structure with Myo-type morphology. The icosahedral head is about 43 nm in diameter. The contracted tail is between 123 nm in length with a myoviral morphology.
GENOME
Circular, dsDNA genome of about 43 kb, encoding for about 79 proteins.
GENE EXPRESSION
Genes are transcribed by operons.
ENZYMES
REPLICATION
CYTOPLASMIC
- 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.
