ricin B-type lectin domain, beta-trefoil fold, found in Clostridium perfringens GlcNac-alpha-1,4-Gal-releasing endo-beta-galactosidase (Endo-beta-Gal(GnGa)) and similar proteins; Endo-beta-Gal(GnGa) can release disaccharide GlcNAc-alpha-1,4Gal from O-glycans expressed in the gastric gland mucous cell-type mucin. It contains a C-terminal ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may harbor a sugar-binding pocket.

glycosyl hydrolase family 16; The O-Glycosyl hydrolases are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A glycosyl hydrolase classification system based on sequence similarity has led to the definition of more than 95 different families inlcuding glycosyl hydrolase family 16. Family 16 includes lichenase, xyloglucan endotransglycosylase (XET), beta-agarase, kappa-carrageenase, endo-beta-1,3-glucanase, endo-beta-1,3-1,4-glucanase, and endo-beta-galactosidase, all of which have a conserved jelly roll fold with a deep active site channel harboring the catalytic residues.

Laminarinase, member of the glycosyl hydrolase family 16; Laminarinase, also known as glucan endo-1,3-beta-D-glucosidase, is a glycosyl hydrolase family 16 member that hydrolyzes 1,3-beta-D-glucosidic linkages in 1,3-beta-D-glucans such as laminarins, curdlans, paramylons, and pachymans, with very limited action on mixed-link (1,3-1,4-)-beta-D-glucans.

Beta-agarase, member of glycosyl hydrolase family 16; Beta-agarase is a glycosyl hydrolase family 16 (GH16) member that hydrolyzes the internal beta-1,4-linkage of agarose, a hydrophilic polysaccharide found in the cell wall of Rhodophyceaea, marine red algae. Agarose is a linear chain of galactose units linked by alternating L-alpha-1,3- and D-beta-1,4-linkages that are additionally modified by a 3,6-anhydro-bridge. Agarose forms thermo-reversible gels that are widely used in the food industry or as a laboratory medium. While beta-agarases are also found in two other families derived from the sequence-based classification of glycosyl hydrolases (GH50, and GH86) the GH16 members are most abundant. This domain adopts a curved beta-sandwich conformation, with a tunnel-shaped active site cavity, referred to as a jellyroll fold.

Coelomic cytolytic factor, member of glycosyl hydrolase family 16; Subgroup of glucanases of unknown function that are related to beta-GRP (beta-1,3-glucan recognition protein), but contain active site residues. Beta-GRPs are one group of pattern recognition receptors (PRRs), also referred to as biosensor proteins, that complexes with pathogen-associated beta-1,3-glucans and then transduces signals necessary for activation of an appropriate innate immune response. Beta-GRPs are present in insects and lack all catalytic residues. This subgroup contains related proteins that still contain the active site and are widely distributed in eukaryotes. Their structures adopt a jelly roll fold with a deep active site channel harboring the catalytic residues, like those of other glycosyl hydrolase family 16 members.

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)
the domain superfamily to which the specific and non-specific hits belong
