''Ravinvirus'' (synonym ''N15-like viruses'', ''N15likevirus'') is a genus of viruses in the order '' Caudovirales'', in the family '' Siphoviridae''. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There is only one species in this genus: ''Escherichia virus N15''.

Structure

Ravinviruses are nonenveloped, with a head and tail. The head is about 60 nm in diameter. The tail is long and flexible, at about 140 nm long, 8 nm wide, with short brush-like terminal fibers.

Genome

''Escherichia virus N15'' has been fully sequenced. It has about 46k nucleotides, with 60 proteins. The complete genome is availabl

Life cycle

Viral replication is cytoplasmic. The virus attaches to the host cell's adhesion receptors using its terminal fiber, and ejects the viral DNA into the host cytoplasm vi

Replication follows the replicative transposition model. 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. Bacteria serve as the natural host. Transmission routes are passive diffusion.

History

According to ICTV, the genus ''N15likevirus'' was first accepted under the name ''N15-like viruses'' i
2004
assigned to family '' Siphoviridae'' in order '' Caudovirales''. I
2012
the genus was renamed to ''N15likevirus''. The genus was later renamed to ''Ravinvirus''.
