enzyme harbors two separate catalytic cores (CD1 and CD2), predicted to have glucansucrase and branching sucrase specificity, respectively. CD2 displays an efficient transglycosidase activity with sucrose as donor substrate. The CD2-catalyzed transglycosylation reaction follows a Ping Pong Bi Bi mechanism and produces single glucosyl (alpha1->3) linked branches onto dextran, resulting in the production of highly branched comb-like alpha-glucan products |

enzyme GtfZ-D2 produces partially branched polymers. Analysis of the glucosyl linkage composition of the (alpha1->3)-branched polymers. Reaction product analyses with 1D 1H NMR, overview. GtfZ-CD2 of Lactobacillus kunkeei uses sucrose as a glucose donor to decorate dextran molecules, adding single (alpha1->3)-branched glucose units on the linear (alpha1->6) glucose chain. GtfZ-CD2 also exhibits (alpha1->3)-branching activity on IMMP (a product of reaction of GtfB, EC 2.4.1.B52, with about 90% (alpha1->6)-linkages) |
