5.4.99.15

Accepted name:

(1→4)-α-D-glucan 1-α-D-glucosylmutase

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.
