cd09216	GH64-LPHase-like	8.17e-154	55	399	1	353	glycoside hydrolase family 64: laminaripentaose-producing, beta-1,3-glucanase (LPHase)-like. This subfamily is represented by the laminaripentaose-producing, beta-1,3-glucanase (LPHase) of Streptomyces matensis and related bacterial and ascomycete proteins. LPHase is a member of glycoside hydrolase family 64 (GH64), it is an inverting enzyme involved in the cleavage of long-chain polysaccharide beta-1,3-glucans, into specific pentasaccharide oligomers. LPHase is a two-domain crescent fold structure: one domain is composed of 10 beta-strands, eight coming from the N-terminus of the protein and two from the C-terminal region, and the protein has a second inserted domain; this cd includes both domains. This protein has an electronegative, substrate-binding cleft, and conserved Glu and Asp residues involved in the cleavage of the beta-1,3-glucan, laminarin, a plant and fungal cell wall component. Among bacteria, many beta-1,3-glucanases are implicated in fungal cell wall degradation. Also included in this family is GluB , the beta-1,3-glucanase B from Lysobacter enzymogenes Strain N4-7. Recombinant GluB demonstrated higher relative activity toward the branched-chain beta-1,3 glucan substrate zymosan A than toward linear beta-1,3 glucan substrates. Sometimes these two domains are found associated with other domains such as in the Catenulispora acidiphila DSM 44928 carbohydrate binding family 6 protein in which they are positioned N-terminal of a carbohydrate binding module, family 6 (CBM_6) domain. In the Cellulosimicrobium cellulans, glucan endo-1,3-beta-glucosidase, they are positioned N-terminal of a RICIN, carbohydrate-binding domain.
pfam16483	Glyco_hydro_64	3.09e-117	53	398	1	370	Beta-1,3-glucanase. Family 64 glycoside hydrolases have beta-1,3-glucanase activity.
cd09220	GH64-GluB-like	5.48e-62	55	398	1	368	glycoside hydrolase family 64: beta-1,3-glucanase B (GluB)-like. This subfamily is represented by GluB, beta-1,3-glucanase B , from Lysobacter enzymogenes Strain N4-7 and related bacterial and ascomycete proteins. GluB is a member of the glycoside hydrolase family 64 (GH64) involved in the cleavage of long-chain polysaccharide beta-1,3-glucans, into specific pentasaccharide oligomers. Among bacteria, many beta-1,3-glucanases are implicated in fungal cell wall degradation. GluB possesses the conserved Glu and Asp residues required to cleave substrate beta-1,3-glucans. Recombinant GluB demonstrated higher relative activity toward the branched-chain beta-1,3 glucan substrate zymosan A than toward linear beta-1,3 glucan substrates. Based on the structure of laminaripentaose-producing, beta-1,3-glucanase (LPHase) of Streptomyces matensis, which belongs to the same family as GluB but to a different subfamily, this cd is a two-domain model. Sometimes these two domains are found associated with other domains such as in the Catenulispora acidiphila DSM 44928 carbohydrate binding family 6 protein in which they are positioned N-terminal of a carbohydrate binding module, family 6 (CBM_6) domain.
cd09214	GH64-like	4.82e-59	55	398	1	318	glycosyl hydrolase 64 family. This family is represented by the laminaripentaose-producing, beta-1,3-glucanase (LPHase) of Streptomyces matensis and related bacterial and ascomycete proteins. LPHase is a member of glycoside hydrolase family 64 (GH64), it is an inverting enzyme involved in the cleavage of long-chain polysaccharide beta-1,3-glucans, into specific pentasaccharide oligomers. LPHase is a two-domain crescent fold structure: one domain is composed of 10 beta-strands, eight coming from the N-terminus of the protein and two from the C-terminal region, and the protein has a second inserted domain; this cd includes both domains.

Sometimes these two domains are found associated with other domains such as in the Catenulispora acidiphila DSM 44928 carbohydrate binding family 6 protein in which they are positioned N-terminal of a carbohydrate binding module, family 6 (CBM_6) domain. In the Cellulosimicrobium cellulans, glucan endo-1,3-beta-glucosidase, they are positioned N-terminal of a RICIN, carbohydrate-binding domain, and in the Salinispora tropica CNB-440, coagulation factor 5/8 C-terminal domain (FA58C) protein, they are positioned C-terminal of two FA58C domains which are proposed to function as cell surface-attached, carbohydrate-binding domain. This FA58C-containing protein has an internal peptide deletion (of approx. 44 residues) in the LPHase domain II.
cd08961	GH64-TLP-SF	8.39e-06	125	209	46	129	glycoside hydrolase family 64 (beta-1,3-glucanases which produce specific pentasaccharide oligomers) and thaumatin-like proteins. This superfamily includes glycoside hydrolases of family 64 (GH64), these are mostly bacterial beta-1,3-glucanases which cleave long-chain polysaccharide beta-1,3-glucans, into specific pentasaccharide oligomers and are implicated in fungal cell wall degradation. Also included in this superfamily are thaumatin, the sweet-tasting protein from the African berry Thaumatococcus daniellii, and thaumatin-like proteins (TLPs) which are involved in host defense and a wide range of developmental processes in fungi, plants, and animals. Like GH64s, some TLPs also hydrolyze the beta-1,3-glucans of the type commonly found in fungal walls. Plant TLPs are classified as pathogenesis-related (PR) protein family 5 (PR5), their expression is induced by environmental stresses such as pathogen/pest attack, drought and cold. Several members of the plant TLP family have been reported as food allergens from fruits, and pollen allergens from conifers. Streptomyces matensis laminaripentaose-producing, beta-1,3-glucanase (GH64-LPHase), and TLPs have in common, a core N-terminal barrel domain (domain I) composed of 10 beta-strands, two coming from the C-terminal region of the protein. In TLPs, this core domain is flanked by two shorter domains (domains II and III). Small TLPs, such as Triticum aestivum thaumatin-like xylanase inhibitor, have a deletion in the third domain (domain II). GH64-LPHase has a second C-terminal domain which corresponds positional to, but is much larger than, domain III of TLP. GH64-LPHase and TLPs are described as crescent-fold structures. Critical functional residues, common to GH64-LPHase and TLPs are a Glu and an Asp residue. LPHase has an electronegative, substrate-binding cleft and the afore mentioned conserved Glu and Asp residues are the catalytic residues essential for beta-1,3-glucan cleavage. In TLPs, these residues are two of the four conserved residues which contribute to the strong electronegative character of the cleft which is associated with the antifungal activity of TLPs.
