oligosaccharide 4-α-D-glucosyltransferase

The enzyme acts on amylose, amylopectin, glycogen and maltooligosaccharides. No detectable free glucose is formed, indicating the enzyme does not act as a hydrolase. The enzyme from the bacterium Cellvibrio japonicus has the highest activity with maltotriose as a donor, and also accepts maltose, while the enzyme from amoeba does not accept maltose. Oligosaccharides with 1→6 linkages cannot function as donors, but can act as acceptors. Unlike EC 2.4.1.25, 4-α-glucanotransferase, this enzyme can transfer only a single glucosyl residue.
