LPS transport system D; Lipopolysaccharide (LPS) is essential for most Gram-negative bacteria and has crucial roles in protection of the bacteria from harsh environments and toxic compounds, including antibiotics. This family includes members such as LPTD found in Shigella flexneri and Yersinia pestis. Structural analysis indicates that LptD forms a novel 26-stranded beta-barrel. It interacts with LPTE where LptE adopts a roll-like structure located inside the barrel of LptD. The LPS translocon LptD is unable to fold properly in the absence of LptE and the two proteins form a unique barrel and plug architecture for LPS transport and insertion. LptD is an essential outer membrane protein that mediates the final transport of lipopolysaccharide (LPS) to outer leaflet. It has been suggested that LptD is a promising target for the development of effective vaccines and antibody-based therapies to control Vibrio infection.

lipopolysaccharide transport periplasmic protein LptA; Members of this protein family include LptA (previously called YhbN). It was shown to be an essential protein in E. coli, implicated in cell envelope integrity, and to play a role in the delivery of LPS to the outer leaflet of the outer membrane. It works with LptB (formerly yhbG), a homolog of ABC transporter ATP-binding proteins, encoded by an adjacent gene. Numerous homologs in other Proteobacteria are found in a conserved location near lipopolysaccharide inner core biosynthesis genes. This family is related to organic solvent tolerance protein (OstA), though distantly.

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.

(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)
