(1-4)-a-D-glucan 1-a-D-glucosylmutase

(1→4)-α- D -Glucan 1-α- D -glucosylmutase (, malto-oligosyltrehalose synthase, maltodextrin alpha-D-glucosyltransferase) is an enzyme with systematic name (1->4)-alpha-D-glucan 1-alpha-D-glucosylmutase. This enzyme catalyses the following chemical reaction


 * 4-[(1->4)-alpha-D-glucosyl]n-1-D-glucose $$\rightleftharpoons$$ 1-alpha-D-[(1->4)-alpha-D-glucosyl]n-1-alpha-D-glucopyranoside

The enzyme from Arthrobacter sp., Sulfolobus acidocaldarius acts on (1->4)-alpha-D-glucans containing three or more (1->4)-alpha-linked D-glucose units.
