Type IV secretory pathway component VirB11-like; Type IV secretory pathway component VirB11, and related ATPases. The homohexamer, VirB11 is one of eleven Vir (virulence) proteins, which are required for T-pilus biogenesis and virulence in the transfer of T-DNA from the bacterial Ti (tumor-inducing)-plasmid into plant cells. The pilus is a fibrous cell surface organelle, which mediates adhesion between bacteria during conjugative transfer or between bacteria and host eukaryotic cells during infection. VirB11-related ATPases include Sulfolobus acidocaldarius FlaI, which plays key roles in archaellum (archaeal flagellum) assembly and motility functions, and the pilus assembly proteins CpaF/TadA and TrbB. This alignment contains the C-terminal domain, which is the ATPase.

P-type DNA transfer ATPase VirB11; The VirB11 protein is found in the vir locus of Agrobacterium Ti plasmids where it is involved in the type IV secretion system for DNA transfer. VirB11 is believed to be an ATPase. VirB11 is a homolog of the P-like conjugation system TrbB protein and the Flp pilus sytem protein TadA.

Type II/IV secretion system protein; This family contains components of both the Type II protein secretion system (T2SS), including Type 4 pilus (T4P), and Type IV protein secretion system (T4SS) from Gram-negative bacteria. VirB11 ATPase is a subunit of the Agrobacterium tumefaciens transfer DNA (T-DNA) transfer system, a type IV secretion pathway required for delivery of T-DNA and effector proteins to plant cells during infection. The cytoplasmic T2S E ATPase is a Zn-containing protein thought to provide the mechanical force for the secretion process. T2S-E contains Walker A and B motifs, that are essential for secretion and ATPase activity. ATPase PulE and XcpR from Klebsiella oxytoca and Pseudomonas aeruginosa respectively are required for protein secretion via the T2SS. ATPase PilB is required for T4P extension.

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.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(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
multi-domain models that were computationally detected and are likely to contain multiple single domains
