additional information	amylomaltases (4-alpha-glucanotransferases) are enzymes which can perform a double-step catalytic process, resulting in a transglycosylation reaction. They hydrolyse glucosidic bonds of alpha-1,4'-D-glucans and transfer the glucan portion with the newly available anomeric carbon to the 4'-position of an alpha-1,4'-D-glucan acceptor.
