Glycosyl hydrolase family 26.

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.

Carbohydrate Binding Module 35 (CBM35) domains similar to Lmo2446. This family includes carbohydrate binding module 35 (CBM35) domains that are appended to several carbohydrate binding enzymes. Some CBM35 domains belonging to this family are appended to glycoside hydrolase (GH) family domains, including glycoside hydrolase family 31 (GH31), for example the CBM35 domain of Lmo2446, an uncharacterized protein from Listeria monocytogenes EGD-e. These CBM35s are non-catalytic carbohydrate binding domains that facilitate the strong binding of the GH catalytic modules with their dedicated, insoluble substrates. GH31 has a wide range of hydrolytic activities such as alpha-glucosidase, alpha-xylosidase, 6-alpha-glucosyltransferase, or alpha-1,4-glucan lyase, cleaving a terminal carbohydrate moiety from a substrate that may be a starch or a glycoprotein. Most characterized GH31 enzymes are alpha-glucosidases.
