Short name: T4SS_VirB5-domain

Overlapping entries


VirB5 proteins are an essential component of most type IV secretion systems. VirB5/TraC is a single domain protein consisting of a three helix bundle and a loose globular appendage [PMID: 14673074]. Structural and functional studies indicate that VirB5 proteins participate in protein-protein interactions important for pilus assembly and function.
