Peduoviridae is a family of viruses in the class Caudoviricetes.[1][2] It was previously treated as a subfamily of the morphology based family Myoviridae, which has been found to be paraphyletic and is no longer recognised.[1] Bacteria serve as natural hosts. There are 126 species in this subfamily, assigned to 58 genera.[2]

Structure

[edit]

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.[3]

Life cycle

[edit]

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.[3]
