(1-4)-a-D-glucan 1-a-D-glucosylmutase
(1->4)-alpha-D-glucan 1-alpha-D-glucosylmutase (EC 5.4.99.15, malto-oligosyltrehalose synthase, maltodextrin alpha-D-glucosyltransferase) is an enzyme with systematic name (1->4)-alpha-D-glucan 1-alpha-D-glucosylmutase.[1][2][3] This enzyme catalyses the following chemical reaction
- 4-[(1->4)-alpha-D-glucosyl]n-1-D-glucose 1-alpha-D-[(1->4)-alpha-D-glucosyl]n-1-alpha-D-glucopyranoside
