Chaacviridae (taxid:3044462)

VIRION

Unknown, discovered using viral metagenomics. Predicted to have tailless icosahedral virion.

• Double jelly roll-fold major capsid protein [MCP]

GENOME

dsDNA genome of 10-11 kb.

GENE EXPRESSION

The genome encodes for about 20 ORFs.

ENZYMES

• DNA-directed DNA polymerase B [POL]

REPLICATION

CYTOPLASMIC

1. Adsorption: the virus attaches to target cell
2. Injection: viral DNA is injected in host cell cytoplasm
3. Transcription and translation of early genes
4. Replication of genomic DNA
5. Transcription and translation of late genes
6. Genomic DNA is packaged in new virions
7. Mature virions are released from the cell by budding through pyramid-like protrusions.
