pfam02156	Glyco_hydro_26	1.44e-38	150	510	1	293	Glycosyl hydrolase family 26.
cd04086	CBM35_mannanase-like	4.70e-12	23	136	3	119	Carbohydrate Binding Module 35 (CBM35); appended to several carbohydrate binding enzymes, including several glycoside hydrolase (GH) family 26 mannanase domains. This family includes carbohydrate binding module 35 (CBM35) domains that are appended to several carbohydrate binding enzymes, including periplasmic component of ABC-type sugar transport system involved in carbohydrate transport and metabolism, and several glycoside hydrolase (GH) domains, including GH26. These CBM6s are non-catalytic carbohydrate binding domains that facilitate the strong binding of the GH catalytic modules with their dedicated, insoluble substrates. Examples of proteins having CMB35s belonging to this family are mannanase A from Clostridium thermocellum (GH26), Man26B from Paenibacillus sp. BME-14 (GH26), and the multifunctional Cel44C-Man26A from Paenibacillus polymyxa GS01 (which has two GH domains, GH44 and GH26). GH26 mainly includes mannan endo-1,4-beta-mannosidase which hydrolyzes 1,4-beta-D-linkages in mannans, galacto-mannans, glucomannans, and galactoglucomannans, but displays little activity towards other plant cell wall polysaccharides. A few proteins belonging to this family have additional CBM3 domains; these CBM3s are not found in the CBM6-CBM35-CBM36_like superfamily.

cd04082	CBM35_pectate_lyase-like	3.17e-07	22	135	2	124	Carbohydrate Binding Module family 35 (CBM35), pectate lyase-like; appended mainly to enzymes that bind mannan (Man), xylan, glucuronic acid (GlcA) and possibly glucans. This family includes carbohydrate binding module family 35 (CBM35) domains that are non-catalytic carbohydrate binding domains that are appended mainly to enzymes that bind mannan (Man), xylan, glucuronic acid (GlcA) and possibly glucans. Included in this family are CBM35s of pectate lyases, including pectate lyase 10A from Cellvibrio japonicas, these enzymes release delta-4,5-anhydrogalaturonic acid (delta4,5-GalA) from pectin, thus identifying a signature molecule for plant cell wall degradation. CBM35s are unique in that they display conserved specificity through extensive sequence similarity but divergent function through their appended catalytic modules. They are known to bind alpha-D-galactose (Gal), mannan (Man), xylan, glucuronic acid (GlcA), a beta-polymer of mannose, and possibly glucans, forming four subfamilies based on general ligand specificities (galacto, urono, manno, and gluco configurations). In contrast to most CBMs that are generally rigid proteins, CBM35 undergoes significant conformational change upon ligand binding. Some CBM35s bind their ligands in a calcium-dependent manner, especially those binding uronic acids.
cd04081	CBM35_galactosidase-like	4.34e-06	23	135	3	125	Carbohydrate Binding Module family 35 (CBM35); appended mainly to enzymes that bind alpha-D-galactose (CBM35-Gal), including glycoside hydrolase (GH) families GH27 and GH43. This family includes carbohydrate binding module family 35 (CBM35); these are non-catalytic carbohydrate binding domains that are appended mainly to enzymes that bind alpha-D-galactose (CBM35-Gal), including glycoside hydrolase (GH) families GH27 and GH43. Examples of proteins which contain CBM35s belonging to this family includes the CBM35 of an exo-beta-1,3-galactanase from Phanerochaete chrysosporium 9 (Pc1,3Gal43A) which is appended to a GH43 domain, and the CBM35 domain of two bifunctional proteins with beta-L-arabinopyranosidase/alpha-D-galactopyranosidase activities from Fusarium oxysporum 12S, Foap1 and Foap2 (Fo/AP1 and Fo/AP2), that are appended to GH27 domains. CBM35s are unique in that they display conserved specificity through extensive sequence similarity but divergent function through their appended catalytic modules. They are known to bind alpha-D-galactose (Gal), mannan (Man), xylan, glucuronic acid (GlcA), a beta-polymer of mannose, and possibly glucans, forming four subfamilies based on general ligand specificities (galacto, urono, manno, and gluco configurations). Some CBM35s bind their ligands in a calcium-dependent manner. In contrast to most CBMs that are generally rigid proteins, CBM35 undergoes significant conformational change upon ligand binding. GH43 includes beta-xylosidases and beta-xylanases, using aryl-glycosides as substrates, while family GH27 includes alpha-galactosidases, alpha-N-acetylgalactosaminidases, and isomaltodextranases.
