ID 3.2.1.204 DE 1,3-alpha-isomaltosidase. CA cyclobis-(1->3)-alpha-D-isomaltosyl + 2 H2O = 2 isomaltose. CC -!- The enzyme, characterized from the bacteria Bacillus sp. CC -!- NRRL B-21195 and Kribbella flavida, participates in the degradation CC of starch. CC -!- The cyclic tetrasaccharide cyclobis-(1->6)-alpha-nigerosyl is formed CC from starch extracellularly and imported into the cell, where it is CC degraded to glucose. DR D2PPM7, AIMA_KRIFD ; //
