SPO1-like viruses

Molecular biology

VIRION

Nonenveloped, head-tail structure. The capsid has a T=16 symmetry . The tails is contractile.

GENOME

Linear, dsDNA genome of about 145 kb, encoding for approximately 200 proteins.

GENE EXPRESSION

Genes are transcribed by operons.

REPLICATION

CYTOPLASMIC

Adsorption: the phage attaches to target cell trhough its tail fibers.
Viral lysozyme degrades cell wall locally
Injection: viral DNA is injected in host cell periplasm by contraction of the tail
Transcription and traduction of early genes
Replication of genomic DNA
Transcription and traduction of late genes
Assembly of new virions in host cell cytoplasm
Mature virions are released from the cell by lysis
