Glycosyl hydrolase family 98. This domain is the putative catalytic domain of glycosyl hydrolase family 98 proteins.

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.

Glycosyl hydrolase family 98 C-terminal domain. This putative domain is found at the C-terminus of glycosyl hydrolase family 98 proteins. This domain is not expected to form part of the catalytic activity.

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.

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.
