enzyme is composed of two functional domains, a catalytic domain: domains A and B, and starch-binding domain: domain C, beta-amylase has three carbohydrate-binding sites aside from the active site: two in domain B named Site2 and Site3, one in domain C named Site1, roles of these sites in the catalytic reaction and raw starch-binding
