Peduovirus


Peduovirus is a genus of viruses in the family Peduoviridae of the class Caudoviricetes. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are 30 recognised species in this genus.

Structure

Peduoviruses are nonenveloped, with a head and tail. The icosahedral head is approximately 60 nm in diameter and a dextral symmetry, composed of 72 capsomers. The tail is around 135 nm long, 18 nm wide, has 6 short, kinked tail fibers. The tail is enclosed in a sheath, which loosens and slides around the tail core upon contraction.

Genome

Nine of the viruses' genomes have been fully sequenced and are available on NCBI's website. They range between 30k and 39k nucleotides, with 40 to 51 proteins. Complete genomes, as well as several additional "unclassified" virus genomes, are available at

Life cycle

Viral replication is cytoplasmic. The virus attaches to the host cell using its tail fibers, and ejects the viral DNA into the host cytoplasm via contraction of its tail sheath. DNA-templated transcription is the method of transcription. Once the viral genes have been replicated, the procapsid is assembled and packed. The tail is then assembled and the mature virions are released via lysis and holin/endolysin/spanin proteins.

History

According to ICTV's 1996 report, the genus P2likevirus was first accepted under the name P2-like phages in the family Myoviridae, unassigned to a sub-family. The genus name was changed to P2-like viruses in the ICTV 7th Report in 1999. It was moved into the subfamily Peduovirinae upon its inception in 2010-11. The following year, the genus was renamed to P2likevirus. These reports are available through ICTV here:,,, . The genus was later renamed to Peduovirus. In 2021, subfamily Peduovirinae was elevated to family Peduoviridae.
