VirB5 protein family; This family contains VirB5 domains, including TraC, a VirB5 homolog encoded by the pKM101 plasmid, and similar proteins. VirB5 is one of 11 conserved proteins (VirB1-VirB11) in Agrobacterium tumefaciens, the causative agent of crown gall disease, that span the inner and the outer membrane, and is involved in type IV DNA secretion systems (T4SS) which mediate the translocation of virulence factors (proteins and/or DNA) from Gram-negative bacteria into eukaryotic cells. VirB5 assembles extracellular pili by interacting with several essential proteins. VirB2-VirB5 complex formation precedes incorporation into pili; it depends on the inner membrane protein VirB4 to interact directly with and stabilize VirB8 in order for VirB5 to bind to VirB8 and VirB10. Mutagenesis studies show that VirB5 proteins participate in protein-protein interactions important for pilus assembly and function.

P-type DNA transfer protein VirB5; The VirB5 protein is involved in the type IV DNA secretion systems typified by the Agrobacterium Ti plasmid vir system where it interacts with several other proteins essential for proper pilus formation. VirB5 is homologous to the IncN (N-type) conjugation system protein TraC as well as the P-type protein TrbJ and the F-type protein TraE.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
