Rod-shaped virion 500nm wide and 1100nm long. The internal membrane is surrounded by a sort of capsid 60nm wide made of 10nm-spaced parallel stripes. The apex appears sealed by a protruding cork 80nm thick and 160nm wide. Source:
Circular, dsDNA genome of about 610kb that encodes for approximately 467 ORFs.
- Virion binds to host cell with the protruding cork, and enters into host cell by phagocytosis
- Fusion of viral envelope with cellular membrane, inducing the release of viral DNA into host cytoplasm.
- Undocumented location of active genome: cytoplasm or nucleus?
- Synthesis of early proteins.
- Replication of genomic DNA.
- Late proteins synthesis, assembly of new virions in the cytoplasmic factories
- Cell lysis and virion release in the extracellular space.
