AIMA is involved in the intracellular degradation of the cyclic tetrasaccharide cyclobis-1-6-alpha ...	This domain is found at the N-terminal 1,3-alpha-isomaltosidase from Kribbella flavida (AIMA, also known as Kfla1895) and sequences from actinomycetes. AIMA is involved in the intracellular degradation of the cyclic tetrasaccharide cyclobis-1-6-alpha-nigerosyl formed extracellularly from starch. It catalyses the hydrolysis of the alpha-1,3-glucosidic linkage of cyclobis-1-6-alpha-nigerosyl to yield isomaltose via a possible linear tetrasaccharide [1]. This domain folds into an Ig-like beta-sandwich.	Domain
