Glucodextranase, domain N 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, hydrolyzing alpha-1,6-glucosidic linkages of dextran to release beta-D-glucose from the non-reducing end via an inverting reaction mechanism. |
