Bcepmuvirus

Bcepmuvirus is a genus of viruses in the family Myoviridae, not assigned to a subfamily. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently two species in this genus, including the type species Burkholderia virus BcepMu.[1][2][3]

Taxonomy

Species:

  • Burkholderia virus BcepMu (type species)
  • Burkholderia virus phiE255

Structure

Bcepmuviruses are nonenveloped, with a head and tail. The head has an elongated icosahedral symmetry (T=13, Q=21).[1]

Genome

Both species have been fully sequenced and are available from ICTV. They range between 36k and 38k nucleotides, with 53 to 55 proteins. The complete genomes are available from here.[3]

Life cycle

The virus attaches to the host cell using its terminal fibers, and ejects the viral DNA into the host cytoplasm via contraction of its tail sheath. 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.[1]

History

According to the ICTV's 2010–11 report, the genus Bcepmuvirus was first accepted as a new genus, at the same time as both of its contained species. This proposal is available here.[2]

gollark: The market system, by giving *each individual participant* a direct incentive to improve things, is more efficient.
gollark: Not the same thing, really.
gollark: Outsourcing *increases* efficiency, which is why it's done.
gollark: In CommunismLand™, if you have a good idea, you must present your good idea to the CommunismCommitee™, who will review it, and then possibly throw it out since it threatens their position, or implement it after about 5 years and when they finish updating plans to include it.
gollark: That's more of a regulatory capture and insufficient personal freedom problem.
