43-333 1.64e-136

glycoside hydrolase family 32 sucrose 6 phosphate hydrolase (sucrase); Glycosyl hydrolase family GH32 subgroup contains sucrose-6-phosphate hydrolase (sucrase, EC:3.2.1.26) among others. The enzyme cleaves sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose. These retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. The breakdown of sucrose is widely used as a carbon or energy source by bacteria, fungi, and plants. Invertase is used commercially in the confectionery industry, since fructose has a sweeter taste than sucrose and a lower tendency to crystallize. A common structural feature of all these enzymes is a 5-bladed beta-propeller domain, similar to GH43, that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.

43-333 1.64e-136

glycoside hydrolase family 32 sucrose 6 phosphate hydrolase (sucrase); Glycosyl hydrolase family GH32 subgroup contains sucrose-6-phosphate hydrolase (sucrase, EC:3.2.1.26) among others. The enzyme cleaves sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose. These retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. The breakdown of sucrose is widely used as a carbon or energy source by bacteria, fungi, and plants. Invertase is used commercially in the confectionery industry, since fructose has a sweeter taste than sucrose and a lower tendency to crystallize. A common structural feature of all these enzymes is a 5-bladed beta-propeller domain, similar to GH43, that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.

43-331 1.55e-68

Glycosyl hydrolase family 32, beta-fructosidases; Glycosyl hydrolase family GH32 cleaves sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose, thus named invertase (EC 3.2.1.26). This family also contains other fructofuranosidases such as inulinase (EC 3.2.1.7), exo-inulinase (EC 3.2.1.80), levanase (EC 3.2.1.65), and transfructosidases such sucrose:sucrose 1-fructosyltransferase (EC 2.4.1.99), fructan:fructan 1-fructosyltransferase (EC 2.4.1.100), sucrose:fructan 6-fructosyltransferase (EC 2.4.1.10), fructan:fructan 6G-fructosyltransferase (EC 2.4.1.243) and levan fructosyltransferases (EC 2.4.1.-). These retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. These enzymes are predicted to display a 5-fold beta-propeller fold as found for GH43 and CH68. The breakdown of sucrose is widely used as a carbon or energy source by bacteria, fungi, and plants. Invertase is used commercially in the confectionery industry, since fructose has a sweeter taste than sucrose and a lower tendency to crystallize. A common structural feature of all these enzymes is a 5-bladed beta-propeller domain, similar to GH43, that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.

glycoside hydrolase family 32 protein such as Aspergillus ficuum endo-inulinase (Inu2); This subfamily of glycosyl hydrolase family GH32 includes endo-inulinase (inu2, EC 3.2.1.7), exo-inulinase (Inu1, EC 3.2.1.80), invertase (EC 3.2.1.26), and levan fructotransferase (LftA, EC 4.2.2.16), among others. These enzymes cleave sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose, thus named invertase (EC 3.2.1.26). These retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. These enzymes are predicted to display a 5-fold beta-propeller fold as found for GH43 and CH68. The breakdown of sucrose is widely used as a carbon or energy source by bacteria, fungi, and plants. Invertase is used commercially in the confectionery industry, since fructose has a sweeter taste than sucrose and a lower tendency to crystallize. A common structural feature of all these enzymes is a 5-bladed beta-propeller domain, similar to GH43, that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.

glycoside hydrolase family 32 protein such as Arabidopsis thaliana cell-wall invertase 1 (AtBFruct1;Fruct1;AtcwINV1;At3g13790); This subfamily of glycosyl hydrolase family GH32 includes fructan beta-(2,1)-fructosidase and fructan 1-exohydrolase IIa (1-FEH IIa, EC 3.2.1.153), cell-wall invertase 1 (EC 3.2.1.26), sucrose:fructan 6-fructosyltransferase (6-Sst/6-Dft, EC 2.4.1.10), and levan fructosyltransferases (EC 2.4.1.-) among others.

Glycosyl hydrolase family 32, such as the putative glycoside hydrolase Escherichia coli Aec43 (FosGH2); This glycosyl hydrolase family 32 (GH32) subgroup includes Escherichia coli strain BEN2908 putative glycoside hydrolase Aec43 (FosGH2). GH32 enzymes cleave sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose, thus named invertase (EC 3.2.1.26). GH32 family also contains other fructofuranosidases such as inulinase (EC 3.2.1.7), exo-inulinase (EC 3.2.1.80), levanase (EC 3.2.1.65), and transfructosidases such sucrose:sucrose 1-fructosyltransferase (EC 2.4.1.99), fructan:fructan 1-fructosyltransferase (EC 2.4.1.100), sucrose:fructan 6-fructosyltransferase (EC 2.4.1.10), fructan:fructan 6G-fructosyltransferase (EC 2.4.1.243) and levan fructosyltransferases (EC 2.4.1.-).

Glycosyl hydrolase families 32 and 68, which form the clan GH-J; This glycosyl hydrolase family clan J (according to carbohydrate-active enzymes database (CAZY)) includes family 32 (GH32) and 68 (GH68). GH32 enzymes include invertase (EC 3.2.1.26) and other other fructofuranosidases such as inulinase (EC 3.2.1.7), exo-inulinase (EC 3.2.1.80), levanase (EC 3.2.1.65), and transfructosidases such sucrose:sucrose 1-fructosyltransferase (EC 2.4.1.99), fructan:fructan 1-fructosyltransferase (EC 2.4.1.100), sucrose:fructan 6-fructosyltransferase (EC 2.4.1.10), fructan:fructan 6G-fructosyltransferase (EC 2.4.1.243) and levan fructosyltransferases (EC 2.4.1.-). The GH68 family consists of frucosyltransferases (FTFs) that include levansucrase (EC 2.4.1.10, also known as beta-D-fructofuranosyl transferase), beta-fructofuranosidase (EC 3.2.1.26) and inulosucrase (EC 2.4.1.9). GH32 and GH68 family enzymes are retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) and catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state.

43-332 1.65e-17

glycoside hydrolase family 32 protein such as Xanthophyllomyces dendrorhous beta-fructofuranosidase (Inv;Xd-INV;XdINV); This subfamily of glycosyl hydrolase family GH32 includes fructan:fructan 1-fructosyltransferase (FT, EC 2.4.1.100) and beta-fructofuranosidase (invertase or Inv, EC 3.2.1.26), among others. These enzymes cleave sucrose into fructose and glucose via beta-fructofuranosidase activity, producing invert sugar that is a mixture of dextrorotatory D-glucose and levorotatory D-fructose, thus named invertase (EC 3.2.1.26). These retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. Xanthophyllomyces dendrorhous beta-fructofuranosidase (XdINV) also catalyzes the synthesis of fructooligosaccharides (FOS, a beneficial prebiotic), producing neo-FOS, making it an interesting biotechnology target. Structural studies show plasticity of its active site, having a flexible loop that is essential in binding sucrose and beta(2-1)-linked oligosaccharide, making it a valuable biocatalyst to produce novel bioconjugates. The breakdown of sucrose is widely used as a carbon or energy source by bacteria, fungi, and plants. Invertase is used commercially in the confectionery industry, since fructose has a sweeter taste than sucrose and a lower tendency to crystallize. A common structural feature of all these enzymes is a 5-bladed beta-propeller domain, similar to GH43, that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.

Glycosyl hydrolase families: GH43, GH62, GH32, GH68, GH117, CH130; Members of the glycosyl hydrolase families 32, 43, 62, 68, 117 and 130 (GH32, GH43, GH62, GH68, GH117, GH130) all possess 5-bladed beta-propeller domains and comprise clans F and J, as classified by the carbohydrate-active enzymes database (CAZY). Clan F consists of families GH43 and GH62. GH43 includes beta-xylosidases (EC 3.2.1.37), beta-xylanases (EC 3.2.1.8), alpha-L-arabinases (EC 3.2.1.99), and alpha-L-arabinofuranosidases (EC 3.2.1.55), using aryl-glycosides as substrates, while family GH62 contains alpha-L-arabinofuranosidases (EC 3.2.1.55) that specifically cleave either alpha-1,2 or alpha-1,3-L-arabinofuranose sidechains from xylans. These are inverting enzymes (i.e. they invert the stereochemistry of the anomeric carbon atom of the substrate) that have an aspartate as the catalytic general base, a glutamate as the catalytic general acid and another aspartate that is responsible for pKa modulation and orienting the catalytic acid. Clan J consists of families GH32 and GH68. GH32 comprises sucrose-6-phosphate hydrolases, invertases (EC 3.2.1.26), inulinases (EC 3.2.1.7), levanases (EC 3.2.1.65), eukaryotic fructosyltransferases, and bacterial fructanotransferases while GH68 consists of frucosyltransferases (FTFs) that include levansucrase (EC 2.4.1.10); beta-fructofuranosidase (EC 3.2.1.26); inulosucrase (EC 2.4.1.9), while GH68 consists of frucosyltransferases (FTFs) that include levansucrase (EC 2.4.1.10); beta-fructofuranosidase (EC 3.2.1.26); inulosucrase (EC 2.4.1.9), all of which use sucrose as their preferential donor substrate. Members of this clan are retaining enzymes (i.e. they retain the configuration at anomeric carbon atom of the substrate) that catalyze hydrolysis in two steps involving a covalent glycosyl enzyme intermediate: an aspartate located close to the N-terminus acts as the catalytic nucleophile and a glutamate acts as the general acid/base; a conserved aspartate residue in the Arg-Asp-Pro (RDP) motif stabilizes the transition state. Structures of all families in the two clans manifest a funnel-shaped active site that comprises two subsites with a single route for access by ligands. Also included in this superfamily are GH117 enzymes that have exo-alpha-1,3-(3,6-anhydro)-l-galactosidase activity, removing terminal non-reducing alpha-1,3-linked 3,6-anhydro-l-galactose residues from their neoagarose substrate, and GH130 that are phosphorylases and hydrolases for beta-mannosides, involved in the bacterial utilization of mannans or N-linked glycans.
