lichenase, member of glycosyl hydrolase family 16; Lichenase, also known as 1,3-1,4-beta-glucanase, is a member of glycosyl hydrolase family 16, that specifically cleaves 1,4-beta-D-glucosidic bonds in mixed-linked beta glucans that also contain 1,3-beta-D-glucosidic linkages. Natural substrates of beta-glucanase are beta-glucans from grain endosperm cell walls or lichenan from the Islandic moss, Cetraria islandica. This protein is found not only in bacteria but also in anaerobic fungi. This domain includes two seven-stranded antiparallel beta-sheets that are adjacent to one another forming a compact, jellyroll beta-sandwich structure.

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.

Xyloglucan endotransglycosylase, member of glycosyl hydrolase family 16; Xyloglucan endotransglycosylases (XETs) cleave and religate xyloglucan polymers in plant cell walls via a transglycosylation mechanism. Xyloglucan is a soluble hemicellulose with a backbone of beta-1,4-linked glucose units, partially substituted with alpha-1,6-linked xylopyranose branches. It binds noncovalently to cellulose, cross-linking the adjacent cellulose microfibrils, giving it a key structural role as a matrix polymer. Therefore, XET plays an important role in all plant processes that require cell wall remodeling.

glycosylphosphatidylinositol-glucanosyltransferase; Group of fungal GH16 members related to Saccharomyces cerevisiae Crh1p. Chr1p and Crh2p are transglycosylases that are required for the linkage of chitin to beta(1-3)glucose branches of beta(1-6)glucan, an important step in the assembly of new cell wall. Both have been shown to be glycosylphosphatidylinositol (GPI)-anchored. A third homologous protein, Crr1p, functions in the formation of the spore wall. They belongs to the family 16 of glycosyl hydrolases that 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.

Kappa-carrageenase, member of glycosyl hydrolase family 16; Kappa-carrageenase is a glycosyl hydrolase family 16 (GH16) member that hydrolyzes the internal beta-1,4-linkage of kappa-carrageenans, a hydrophilic polysaccharide found in the cell wall of Rhodophyceaea, marine red algae. Carrageenans are linear chains of galactose units linked by alternating D-alpha-1,3- and D-beta-1,4-linkages that are additionally modified by a 3,6-anhydro-bridge. Depending on the position and number of sulfate ester modifications they are subdivided into kappa-, iota-, and lambda-carrageenases, kappa being modified once. Carrageenans form thermo-reversible gels widely used for industrial applications. Kappa-carrageenases exist in bacteria belonging to at least three phylogenetically distant branches, including pseudoalteromonas, planctomycetes, and baceroidetes. This domain adopts a curved beta-sandwich conformation, with a tunnel-shaped active site cavity, referred to as a jellyroll fold.
