Glycosyl hydrolase family 49 N-terminal Ig-like domain. Family of dextranase (EC 3.2.1.11) and isopullulanase (EC 3.2.1.57). Dextranase hydrolyzes alpha-1,6-glycosidic bonds in dextran polymers. This domain corresponds to the N-terminal Ig-like fold.

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.

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 family 49. Family of dextranase (EC 3.2.1.11) and isopullulanase (EC 3.2.1.57). Dextranase hydrolyzes alpha-1,6-glycosidic bonds in dextran polymers. This domain corresponds to the C-terminal pectate lyase like domain.

Isopullulanase beta-solenoid repeat. IPU and dextranase repeat unit includes three (or one long and one short) parallel beta-strands. The repeat region as a whole folds into a beta-helix, known as beta-solenoid.
