NATE-0304
Description
A moderately thermostable Glucansucrase (4,6-Alpha-Glucanotransferase, reuteransucrase). The enzyme transfers glucose units from sucrose to make a highly branched, high molecular weight alpha-D-Glucan with α (1→4) glucosidic linkages and also some α (1→6) linked glucosyl units.
