281639	Glyco_hydro_62	9.45e-168	28	298	1	272	Glycosyl hydrolase family 62. Family of alpha -L-arabinofuranosidase (EC 3.2.1.55). This enzyme hydrolyzed aryl alpha-L-arabinofuranosides and cleaves arabinosyl side chains from arabinoxylan and arabinan.
350101	GH62	1.07e-144	30	321	1	299	Glycosyl hydrolase family 62, characterized arabinofuranosidases. The glycosyl hydrolase family 62 (GH62) includes eukaryotic (mostly fungal) and prokaryotic enzymes which are characterized arabinofuranosidases (alpha-L-arabinofuranosidases; EC 3.2.1.55) that specifically cleave either alpha-1,2 or alpha-1,3-L-arabinofuranose side chains from xylans. These enzymes show significantly different substrate preference with rather low specific activity towards natural substrates and differ in catalytic efficiency. They do not act on xylose moieties in xylan that are adorned with an arabinose side chain at both O2 and O3 positions, nor do they display any non-specific arabinofuranosidase activity. The synergistic action in biomass degradation makes GH62 promising candidates for biotechnological improvements of biofuel production and in various biorefinery applications. These enzymes also contain carbohydrate binding modules (CBMs) that bind cellulose or xylan.
350092	GH_F	8.77e-32	53	306	1	251	Glycosyl hydrolase families 43 and 62 form CAZY clan GH-F. This glycosyl hydrolase clan F (according to carbohydrate-active enzymes database (CAZY)) includes family 43 (GH43) and 62 (GH62). GH43 includes enzymes with beta-xylosidase (EC 3.2.1.37), beta-1,3-xylosidase (EC 3.2.1.-), alpha-L-arabinofuranosidase (EC 3.2.1.55), arabinanase (EC 3.2.1.99), xylanase (EC 3.2.1.8), endo-alpha-L-arabinanases (beta-xylanases) and galactan 1,3-beta-galactosidase (EC 3.2.1.145) activities. GH62 includes enzymes characterized as arabinofuranosidases (alpha-L-arabinofuranosidases; EC 3.2.1.55) that specifically cleave either alpha-1,2 or alpha-1,3-L-arabinofuranose side chains from xylans. 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 of the enzymes in this family display both alpha-L-arabinofuranosidase and beta-D-xylosidase activity using aryl-glycosides as substrates. GH62 are also predicted to be inverting enzymes. A common structural feature of both, GH43 and GH62 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.
