General Information

EC Number General Information Comment Organism
2.4.1.248 physiological function CITase production is induced by dextran 40, isomaltose, isomaltotriose, and panose, and soluble starch but not by G67 or dextrin, which suggests that alpha-1,6 glucosidic linkages are required for CITase induction. Although CITase is induced by isomaltose, isomaltotriose, and panose, no cyclodextrans are produced in the culture. Cyclodextran-producing activity in the presence of soluble starch as the substrate is observed only in cultures containing dextran 40 or soluble starch. The production of CITase is significantly unaffected by glucose addition, but soluble starch-CITase activity almost completely disappears after glucose addition. A 135-kDa protein contributes to cyclodextran formation from starch in the presence of CITase Niallia circulans
