TrwB/TraG/TraD/VirD4 family of bacterial conjugation proteins; The TraG/TraD/VirD4 family are bacterial conjugation proteins involved in type IV secretion (T4S) systems, versatile bacterial secretion systems mediating transport of protein and/or DNA. They are present in gram-negative and gram-positive bacteria, as well as archaea. They form hexameric rings and belong to the RecA-like NTPases superfamily, which also includes the NTP binding domain of F1 and V1 H(+)ATPases, DnaB and related helicases as well as bacterial RecA and related eukaryotic and archaeal recombinases.

type IV secretion/conjugal transfer ATPase, VirB4 family; Type IV secretion systems are found in Gram-negative pathogens. They export proteins, DNA, or complexes in different systems and are related to plasmid conjugation systems. This model represents related ATPases that include VirB4 in Agrobacterium tumefaciens (DNA export) CagE in Helicobacter pylori (protein export) and plasmid TraB (conjugation).

AAA-like domain; This family of domains contain a P-loop motif that is characteriztic of the AAA superfamily. Many of the proteins in this family are conjugative transfer proteins, including VirB4 components of the Type IV secretory pathway and conjugal transfer protein TrbE. This entry includes the arcaheal Vir4/HerA homolog CedB, a membrane-bound protein that is highly induced upon UV treatment and essential for DNA transfer between Sulfolobus cells.

Helicase HerA, central domain; This entry represents the central domain found in archaeal proteins such as DNA double-strand break repair helicase HerA (EC:3.6.4.12). HerA is a helicase which is able to utilize either 3' or 5' single-stranded DNA extensions for loading and subsequent DNA duplex unwinding. It forms a complex with NurA nuclease, this complex has the 5'-3' DNA end resection activity and is essential for cell viability in the crenarchaeon Sulfolobus islandicus. This domain includes the the central RecA-like catalytic core and a flanking four-helix bundle. The function of this prokaryotic domain is unknown. It contains several conserved aspartates and histidines that could be metal ligands.

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.

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.

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) 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)
