C-terminus of bacterial fibrinogen-binding adhesin; This is the C-terminal half of a bacterial fibrinogen-binding adhesin SdrG. SdrG is a Gram-positive cell-wall-anchored adhesin that allows attachment of the bacterium to host tissues via specific binding to the beta-chain of human fibrinogen (Fg). SdrG binds to its ligand with a dynamic "dock, lock, and latch" mechanism which represents a general mode of ligand-binding for structurally related cell wall-anchored proteins in most Gram-positive bacteria. The C-terminal part of SdrG(276-596) is integral to the folding of the immunoglobulin-like whole to create the docking grooves necessary for Fg binding. The domain is associated with families of Cna_B, pfam05738.

MSCRAMM family adhesin clumping factor ClfA; Clumping factor A is an MSCRAMM (Microbial Surface Components Recognizing Adhesive Matrix Molecules). It is heavily studied in Staphylococcus aureus both for its biological role in adhesion and for its potential for vaccination. Features of the sequence, but also of other MSCRAMM adhesins, include a long run of Ser-Asp dipeptide repeats and a C-terminal cell wall anchoring LPXTG motif.

Gram-positive signal peptide, YSIRK family; Many surface proteins found in Streptococcus, Staphylococcus, and related lineages share apparently homologous signal sequences. A motif resembling [YF]SIRKxxxGxxS[VIA] appears at the start of the transmembrane domain. The GxxS motif appears perfectly conserved, suggesting a specific function and not just homology. There is a strong correlation between proteins carrying this region at the N-terminus and those carrying the Gram-positive anchor domain with the LPXTG sortase processing site at the C-terminus.

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) 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
