cd18620	GH43_XylA-like	1.59e-107	50	361	1	271	Glycosyl hydrolase family 43-like protein such as Clostridium stercorarium alpha-L-arabinofuranosidase XylA. This glycosyl hydrolase family 43 (GH43) subgroup belongs to the GH43_AXH-like subgroup which includes enzymes that have been characterized with beta-xylosidase (EC 3.2.1.37), alpha-L-arabinofuranosidase (EC 3.2.1.55), alpha-1,2-L-arabinofuranosidase 43A (arabinan-specific; EC 3.2.1.-), endo-alpha-L-arabinanase as well as arabinoxylan arabinofuranohydrolase (AXH) activities. GH43 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. Many GH43 enzymes display both alpha-L-arabinofuranosidase and beta-D-xylosidase activity using aryl-glycosides as substrates. The GH43_XylA-like subgroup includes Clostridium stercorarium alpha-L-arabinofuranosidase XylA, and enzymes that have been annotated as having beta-xylosidase (EC 3.2.1.37), alpha-L-arabinofuranosidase (EC 3.2.1.55), endo-alpha-L-arabinanase (EC 3.2.1.-) as well as arabinoxylan arabinofuranohydrolase (AXH) activities. GH43 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. Many GH43 enzymes display both alpha-L-arabinofuranosidase and beta-D-xylosidase activity using aryl-glycosides as substrates. AXHs specifically hydrolyze the glycosidic bond between arabinofuranosyl substituents and xylopyranosyl backbone residues of arabinoxylan.
cd08990	GH43_AXH_like	4.60e-50	51	354	2	260	Glycosyl hydrolase family 43 protein, includes arabinoxylan arabinofuranohydrolase, beta-xylosidase, endo-1,4-beta-xylanase, and alpha-L-arabinofuranosidase. This subgroup includes Bacillus subtilis arabinoxylan arabinofuranohydrolase (XynD;BsAXH-m23;BSU18160), Butyrivibrio proteoclasticus alpha-L-arabinofuranosidase (Xsa43E;bpr_I2319), Clostridium stercorarium alpha-L-arabinofuranosidase XylA, and metagenomic beta-xylosidase (EC 3.2.1.37) / alpha-L-arabinofuranosidase (EC 3.2.1.55) CoXyl43. It belongs to the glycosyl hydrolase clan F (according to carbohydrate-active enzymes database (CAZY)) which includes family 43 (GH43) and 62 (GH62) families. The GH43_AXH-like subgroup includes enzymes that have been characterized with beta-xylosidase, alpha-L-arabinofuranosidase, endo-alpha-L-arabinanase as well as arabinoxylan arabinofuranohydrolase (AXH) activities. GH43 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. Many GH43 enzymes display both alpha-L-arabinofuranosidase and beta-D-xylosidase activity using aryl-glycosides as substrates. AXHs specifically hydrolyze the glycosidic bond between arabinofuranosyl substituents and xylopyranosyl backbone residues of arabinoxylan. Metagenomic beta-xylosidase/alpha-L-arabinofuranosidase CoXyl43 shows synergy with Trichoderma reesei cellulases and promotes plant biomass saccharification by degrading xylo-oligosaccharides, such as xylobiose and xylotriose, into the monosaccharide xylose. Studies show that the hydrolytic activity of CoXyl43 is stimulated in the presence of calcium. Several of these enzymes also contain carbohydrate binding modules (CBMs) that bind cellulose or xylan. A common structural feature of GH43 enzymes is a 5-bladed beta-propeller domain 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.
cd09003	GH43_XynD-like	9.66e-38	67	339	20	284	Glycosyl hydrolase family 43 protein such as Bacillus subtilis arabinoxylan arabinofuranohydrolase (XynD;BsAXH-m23;BSU18160). This glycosyl hydrolase family 43 (GH43) subgroup includes characterized Bacillus subtilis arabinoxylan arabinofuranohydrolase (AXH), Caldicellulosiruptor sp. Tok7B.1 beta-1,4-xylanase (EC 3.2.1.8) / alpha-L-arabinosidase (EC 3.2.1.55) XynA, Caldicellulosiruptor sp. Rt69B.1 xylanase C (EC 3.2.1.8) XynC, and Caldicellulosiruptor saccharolyticus beta-xylosidase (EC 3.2.1.37)/ alpha-L-arabinofuranosidase (EC 3.2.1.55) XynF. It belongs to the glycosyl hydrolase clan F (according to carbohydrate-active enzymes database (CAZY)) which includes family 43 (GH43) and 62 (GH62) families. It belongs to the GH43_AXH-like subgroup which includes enzymes that have been annotated as having beta-xylosidase, alpha-L-arabinofuranosidase and arabinoxylan alpha-L-1,3-arabinofuranohydrolase, xylanase (endo-alpha-L-arabinanase) as well as AXH activities. GH43 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. Many GH43 enzymes display both alpha-L-arabinofuranosidase and beta-D-xylosidase activity using aryl-glycosides as substrates. AXHs specifically hydrolyze the glycosidic bond between arabinofuranosyl substituents and xylopyranosyl backbone residues of arabinoxylan. Bacillus subtilis AXH (BsAXH-m2,3) has been shown to cleave arabinose units from O-2- or O-3-mono-substituted xylose residues and superposition of its structure with known structures of the GH43 exo-acting enzymes, beta-xylosidase and alpha-L-arabinanase, each in complex with their substrate, reveals a different orientation of the sugar backbone. Several of these enzymes also contain carbohydrate binding modules (CBMs) that bind cellulose or xylan. A common structural feature of GH43 enzymes is a 5-bladed beta-propeller domain 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.

cd18618	GH43_Xsa43E-like	4.93e-28	50	336	3	246	Glycosyl hydrolase family 43, including Butyrivibrio proteoclasticus arabinofuranosidase Xsa43E. This glycosyl hydrolase family 43 (GH43) subgroup belongs to the GH43_AXH-like subgroup which includes enzymes that have been characterized with beta-xylosidase (EC 3.2.1.37), alpha-L-arabinofuranosidase (EC 3.2.1.55), alpha-1,2-L-arabinofuranosidase 43A (arabinan-specific; EC 3.2.1.-), endo-alpha-L-arabinanase as well as arabinoxylan arabinofuranohydrolase (AXH) activities.

AXHs specifically hydrolyze the glycosidic bond between arabinofuranosyl substituents and xylopyranosyl backbone residues of arabinoxylan. This subgroup includes Cellvibrio japonicus arabinan-specific alpha-1,2-arabinofuranosidase, CjAbf43A, which confers its specificity by a surface cleft that is complementary to the helical backbone of the polysaccharide, and Butyrivibrio proteoclasticus GH43 enzyme Xsa43E, also an arabinofuranosidase, which has been shown to cleave arabinose side chains from short segments of xylan. Several of these enzymes also contain carbohydrate binding modules (CBMs) that bind cellulose or xylan. A common structural feature of GH43 enzymes is a 5-bladed beta-propeller domain 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.
