Accepted name: | 1,3-α-isomaltosidase | ||||
Reaction: | cyclobis-(1→6)-α-nigerosyl + 2 H2O = 2 isomaltose (overall reaction) (1a) cyclobis-(1→6)-α-nigerosyl + H2O = α-isomaltosyl-(1→3)-isomaltose (1b) α-isomaltosyl-(1→3)-isomaltose + H2O = 2 isomaltose |
||||
Systematic name: | 1,3-α-isomaltohydrolase (configuration-retaining) | ||||
Comments: | 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)-α-nigerosyl is formed from starch extracellularly and imported into the cell, where it is degraded to glucose. | ||||
