Uetakevirus (taxid:542960)

VIRION

Non-enveloped, head-tail structure. Head is about 70 nm in diameter, with a T=7 icosahedral symmetry . The tail is short (about 17 nm), non-contractile, has 6 prominent tail spikes.

GENOME

Linear, dsDNA genome of about 40 kb encoding for 51 genes.

GENE EXPRESSION

REPLICATION

CYTOPLASMIC

1. Adsorption: the phage attaches to the target cell through its tail fibers.
2. Ejection of the viral DNA into host cell cytoplasm.
3. Transcription and translation of early genes.
4. Replication of genomic DNA. Transcription and translation of late genes.
5. Assembly of an empty procapsid and packaging of the genome.
6. Viral tail fibers assembly and viral tail assembly.
7. Mature virions are released from the cell by lysis.
