alpha-(1,4)-glycosidic linked cyclodextrins + H2O
maltooligosaccharide
-
main depolymerization of outer amylopectin branches
-
-
?
amylopectin + H2O
fragments of amylopectin + dextrin
-
main depolymerization of outer amylopectin branches
mainly short amylopectin chains from degradation of outer branches, inhibiting amylopectin retrogradation, and therefore, amorphous starch network and week amylose network of freshly baked bread are retained
-
?
maltotriose + H2O
isomaltose + isopanose + panose + branched glucooligosaccharides
-
-
transfer products of transglycosylation
-
?
additional information
?
-
-
BSMA preferentially hydrolyzes longer branch chains, releasing maltose and glucose from the non-reducing end of the branch chains, and transfers the resulting maltooligosaccharides to the non-reducing ends of the shorter branch chains by forming alpha-1,6-glucosidic linkages

amylopectin + H2O
maltose + maltotriose
-
-
wild-type enzyme produces 93% maltose (2 homomers) and 5% maltotriose compared to 66% maltose and 20% maltotriose of mutant F188L/D261G/T288P
