ENZYME entry: EC 3.2.1.204

Accepted Name
1,3-alpha-isomaltosidase.
Reaction catalysed
cyclobis-(1->3)-alpha-D-isomaltosyl + 2 H2O <=> 2 isomaltose
Comment(s)
  • The enzyme, characterized from the bacteria Bacillus sp.
  • NRRL B-21195 and Kribbella flavida, participates in the degradation of starch.
  • The cyclic tetrasaccharide cyclobis-(1->6)-alpha-nigerosyl is formed from starch extracellularly and imported into the cell, where it is degraded to glucose.
