• The purified debranching enzyme of rice seeds has been studied to determine its action on starch-like polysaccharides. An endo-fashion degradation was demonstrated that produced branched saccharides; however, a large quantity of maltose and maltotriose were produced from the β-limit dextrin of glutinous rice starch, even at an early stage of reaction. The V of the enzyme for β-limit dextrin was ten-times larger than that for glutinous rice starch, which suggests that the rapid liberation of A-chains in the β-limit dextrin may be due to their chain length rather than to their occurrence at the exo-position.
