The mechanism of the action of amylosynthease was examined, and following evidences were discovered: (1) The presence of inorganic phosphate has no influence upon the enzyme activity. (2) The enzyme has no hydrolytic action on bacterial dextrans, produced by Leuconostoc mesenteroides. (3) The presence of branching points at 1, 6-linkages in the substrate is necessary for this enzyme to develop its action. It was concluded that this enzyme did not belong to phosphorylase, nor to dextranase, but rather to an amylase of particular type. The authors' theory on the mechanism of the action, that it attacks the branching points of glucosidic chains, was again confirmed. For this enzyme a new name "isoamylase" is proposed.
