VIRION
Presumably non-enveloped, head-tail structure with Sipho-type morphology.
GENOME
Linear, dsDNA genome of about 32-37 kb.
GENE EXPRESSION
ENZYMES
- Methyltransferase [MetT1, MetT2]
- Terminase [TermL]
- Cysteine protease (Peptidase S78) [Pro]
REPLICATION
CYTOPLASMIC
- Adsorption: The phage attaches to target cell adhesion receptors 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.
- Transcription and translation of late genes
- Assembly of an empty procapsid and packaging of the genome.
- Viral tail fiber assembly and viral tail assembly.
- Mature virions are released from the cell by lysis.
