Glycoside hydrolase 97. This domain is the catalytic region of the bacterial glycosyl-hydrolase family 97. This central part of the GH97 family protein sequences represents a typical and complete (beta/alpha)8-barrel or catalytic TIM-barrel type domain. The N- and C-terminal parts of the sequences, mainly consisting of beta-strands, form two additional non-catalytic domains. In all known glycosidases with the (beta-alpha)8-barrel fold, the amino acid residues at the active site are located on the C-termini of the beta-strands.

C-terminal binding-module, SLH-like, of glucodextranase. Glucodextran_C is the C-terminal domain of glucodextranase-like proteins found in various prokaryotic membrane-anchored proteins. It shows homology to the carbohydrate-binding unit of some glycosidases.

Glycosyl-hydrolase 97 N-terminal. This N-terminal domain of glycosyl-hydrolase-97 contributes part of the active site pocket. It is also important for contact with the catalytic and C-terminal domains of the whole.

DOMON-like domain of various glycoside hydrolases. This DOMON-like domain is found at the C-terminus of various bacterial proteins that play roles in metabolizing carbohydrates, such as glucodextranase (hydrolyzes alpha-1,6-glucosidic linkages of dextran from the non-reducing end), glucan alpha-1,4-glucosidase, pullulanase (degrades pullulan, a polysaccharide built from maltotriose units), arabinogalactan endo-1,4-beta-galactosidase, and others. Consequently, the DOMON-like domains in this family co-occur with catalytic domains from various glycosyl hydrolase families. The precise function of the DOMON domains in these proteins is not clear, they may be involved in interactions with carbohydrates.

Glycosyl-hydrolase 97 C-terminal, oligomerization. Glycosyl-hydrolase-97 is made up of three tightly linked and highly conserved globular domains. The C-terminal domain is found to be necessary for oligomerization of the whole molecule in order to create the active-site pocket and the Ca++-binding site.
