Rauchvirus
Genus of viruses
From Wikipedia, the free encyclopedia
Rauchvirus is a genus of viruses in the class Caudoviricetes. Bacteria serve as natural hosts. The genus contains only one species: Rauchvirus BPP1.[1][2]

Structure
Viruses in Rauchvirus are non-enveloped, with icosahedral and head-tail geometries, and T=7 symmetry. The diameter is around 67 nm. Genomes are linear, around 42kb in length, and usually encodes about 50 proteins. The Bordetella phages of this genus contains an RNA-directed DNA polymerase which plays a role in tropism.[1][3] [4]
The genomes are linear, terminally redundant, and circularly with approximately 40.[5] There are 53 proteins, and genes are arrayed in two transcriptional units, one on the negative strand, which is involved in regulation and recombination; the other is located on the positive strand which is involved in packaging, morphogenesis, lysis and integration.[3]

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. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
