Keywords navigation

Broader

Definition

Viral protein that constitutes the noncontractile ejection system carried by some long-tailed prokaryotic viruses such as the Siphoviridae. This ejection system is composed at least of a noncontractile tube and a tail tip which is able to penetrate the host cell envelope to deliver the viral genome, and possibly some specific proteins, into the cell cytoplasm. Proteins of the ejection apparatus can play an active or a structural role in ejection.

Synonyms

  • Viral genome injection via long noncontractile tail
