Reaction: 4-[(1→4)-α-D-glucosyl]n-1-D-glucose = 1-α-D-[(1→4)-α-D-glucosyl]n-1-α-D-glucopyranoside
Other name(s): malto-oligosyltrehalose synthase; maltodextrin α-D-glucosyltransferase
Systematic name: (1→4)-α-D-glucan 1-α-D-glucosylmutase
Comments: The enzyme from Arthrobacter sp., Sulfolobus acidocaldarius acts on (1→4)-α-D-glucans containing three or more (1→4)-α-linked D-glucose units. Not active towards maltose.
