Structure

Viruses in Peduovirinae are non-enveloped, with icosahedral and Head-tail geometries, and T=7 symmetry. The diameter is around 60 nm. Genomes are linear, around 33kb in length. The genome codes for 45 proteins.^[1]

Genus	Structure	Symmetry	Capsid	Genomic Arrangement	Genomic Segmentation
P2likevirus	Head-Tail	T=7 dextro	Non-Enveloped	Linear	Monopartite
Hpunalikevirus	Head-Tail	T=7	Non-Enveloped	Linear	Monopartite

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. The virus exits the host cell by lysis, and holin/endolysin/spanin proteins. Bacteria serve as the natural host. Transmission routes are passive diffusion. ^[1]

Genus	Host Details	Tissue Tropism	Entry Details	Release Details	Replication Site	Assembly Site	Transmission
P2likevirus	Bacteria	None	Injection	Lysis	Cytoplasm	Cytoplasm	Passive diffusion
Hpunalikevirus	Bacteria	None	Injection	Lysis	Cytoplasm	Cytoplasm	Passive diffusion
