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;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the disproportionating enzyme family.
CC       {ECO:0000305}.
