Function and Biology Details

Reaction catalysed:
Transfers the non-reducing terminal alpha-D-glucose residue from a (1->4)-alpha-D-glucan to the 4-position of a free glucose or of a glucosyl residue at the non-reducing terminus of a (1->4)-alpha-D-glucan, thus bringing about the rearrangement of oligosaccharides
