Members of this family adopt a structure consisting of seven/eight-strand antiparallel beta-sheets, in a Greek-key topology, similar to the immunoglobulin beta-sandwich fold. They act as cell wall anchors, where they interact with the S-layer present in the cell wall of Gram-positive bacteria by hydrophobic interactions. In glucodextranase, Domain B is buried in the S-layer, and a flexible linker located between domain B and the catalytic unit confers motion to the catalytic unit, which is capable of efficient hydrolysis of the substrates located close to the cell surface [1].

Members of this family, which are uniquely found in bacterial and archaeal glucoamylases and glucodextranases, adopt a structure consisting of 17 antiparallel beta-strands. These beta-strands are divided into two beta-sheets, and one of the beta-sheets is wrapped by an extended polypeptide, which appears to stabilise the domain. Members of this family are mainly concerned with catalytic activity, hydrolysing alpha-1,6-glucosidic linkages of dextran to release beta-D-glucose from the non-reducing end via an inverting reaction mechanism [1].
