type IVB pilus formation outer membrane protein, R64 PilN family; Several related protein families encode outer membrane pore proteins for type II secretion, type III secretion, and type IV pilus formation. This protein family appears to encode a secretin for pilus formation, although it is quite different from PilQ. Members include the PilN lipoprotein of the plasmid R64 thin pilus, a type IV pilus. Scoring between the trusted and noise cutoffs are examples of bundle-forming pilus B (bfpB). [Cell envelope, Surface structures, Protein fate, Protein and peptide secretion and trafficking]

pilus (MSHA type) biogenesis protein MshL; Members of this family are predicted secretins, that is, outer membrane pore proteins associated with delivery of proteins from periplasm to the outside of the cell. Related families include GspD of type II secretion (TIGR02517), the YscC/HrcC family from type III secretion (TIGR02516), and the PilQ secretin of type IV pilus formation (TIGR02515). Members of this family are found in gene clusters associated with MSHA (mannose-sensitive hemagglutinin) and related pili, and appear to be the secretin of this pilus system.

type II secretion system protein D; In Gram-negative bacteria, proteins that have first crossed the inner member by Sec-dependent protein transport can be exported across the outer membrane by type II secretion, also called the main terminal branch of the general secretion pathway. Members of this family are general secretion pathway protein D. In Yersinia enterocolitica, a second member of this family is part of a novel second type II secretion system specifically associated with virulence (See ). This family is closely homologous to the type IV pilus outer membrane secretin PilQ (TIGR02515) and to the type III secretion system pore YscC/HrcC (TIGR02516).

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,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
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
