Specifications

Exoenzyme that releases successive maltose units from the nonreducing end of a polysaccharide chain by hydrolysis of a 1,4-glucan linkages. The shortest normal saccharide attacked is maltotetraose. Since it is unable to bypass branch linkages in branched polysaccharides such as glycogen or amylopectin, the hydrolysis is incomplete and a macromolecular limit dextrin remains.
Catalog #A2275-50
Found primarily in the seeds of higher plants and sweet potatoes. It yields a single product maltose. The enzyme is useful in structural studies of starch and glycogen.
