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)

alpha(1->2) or alpha(1->3) branched dextrans with high molar masses and controlled architecture are synthesized using dextransucrase from Oenococcous kitahare DSM 17330 (DSR-OK), the branching sucrase from Leuconostoc citreum NRRL B-1299 (BRS-A) and the branching sucrase from Leuconostoc citreum NRRL B-742 (BRS-BDELTA1), all in cell-free extract from recombinant Escherichia coli strain BL21. Their molecular structure, solubility, conformation, film-forming ability, as well as their thermal and mechanical properties are determined, detailed overview. The pattern of the molar mass increase depends on the branching degree and the branching type, probably because of the different conformations due to the different flexibility and hindrance introduced by either the alpha(1->2) or the alpha(1->3) linkages
