CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Transfers a segment of a (1->4)-alpha-D-glucan to a new
CC         position in an acceptor, which may be glucose or a (1->4)-alpha-D-
CC         glucan.; EC=2.4.1.25; Evidence={ECO:0000256|ARBA:ARBA00000439,
CC         ECO:0000256|RuleBase:RU361207};
CC   -!- SIMILARITY: Belongs to the disproportionating enzyme family.
