This entry represents two tandem carbohydrate binding domains from CBM17 and CBM28 families. CBM17 binds to amorphous cellulose and soluble beta-1,4-glucans. CBM28 does not compete with CBM17 modules when binding to non-crystalline cellulose and it is closely related to CBM17, according to sequence and structural conservation which suggests that they have evolved through gene duplication and subsequent divergence.
