| Native Leuconostoc mesenteroides Dextran Sucrase | Dextransucrases are glucansucrases that are able to produce dextran, a glucose polymer linked mainly through α1-6 bonds. However, α1-3, α1-6, α1-4 and α1-2 bonds are also found, in both the main chain and the branching linkages. The peptide has approximately 1600 amino acids. The aspartic acid in position 551 is essential for catalytic activity, while glutamic acid 589 and aspartic acid 662 complement the catalytic triad. The activity of dextransucrase is decreased by EDTA, and is restored by the addition of calcium ions. Zinc, cadmium, lead, mercury and copper ions are inhibitory to various degrees. Applications: Dextran sucrase from leu. immobilized sphere for the production of dextran from sucrose. Group: Enzymes. Synonyms: EC 2.4.1.5, sucrose 6-glucosyltransferase; SGE; CEP; sucrose-1,6-α-glucan glucosyltransferase; sucrose:1,6-α-D-glucan 6-α-D-glucosyltransferase; 9032-14-8. Enzyme Commission Number: EC 2.4.1.5. CAS No. 9032-14-8. SGE. Activity: > 100 units/mg protein. Storage: -20°C. Form: Lyophilized powder containing dextran, MES buffer salts and CaCl2. Source: Leuconostoc mesenteroides. EC 2.4.1.5, sucrose 6-glucosyltransferase; SGE; CEP; sucrose-1,6-α-glucan glucosyltransferase; sucrose:1,6-α-D-glucan 6-α-D-glucosyltransferase; 9032-14-8. Cat No: NATE-0669. | |
| sucrose-1,6-α-glucan 3(6)-α-glucosyltransferase | The enzyme was characterized from the dental caries bacterium Streptococcus mutans. It transfers glucosyl residues from sucrose to either the 6- or the 3-positions of glucose residues in glucans, producing a highly-branched extracellular D-glucan polymers that promote attachment of the bacteria to teeth. Three types of the enzyme have been described; the insoluble polymers produced by GTF-I and GTF-SI contain 85% α(1?3) bonds and 15% α(1?6) bonds, while the soluble polymers produced by GTF-S contain only 30% of α(1?3) bonds and 70% α(1?6) bonds. cf. EC 2.4.1.5, dextransucrase. Group: Enzymes. Synony. Enzyme Commission Number: EC 2.4.1.125. CAS No. 81725-87-3. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2350; sucrose-1,6-α-glucan 3(6)-α-glucosyltransferase; EC 2.4.1.125; 81725-87-3; water-soluble-glucan synthase (misleading); GTF-I; GTF-S; GTF-SI; sucrose-1,6-α-glucan 3(6)-α-glucosyltransferase; sucrose:1,6-α-D-glucan 3-α- and 6-α-glucosyltransferase; sucrose:1,6-, 1,3-α-D-glucan 3-α- and 6-α-D-glucosyltransferase; sucrose:1,6-α-D-glucan 3(6)-α-D-glucosyltransferase; gtfB (gene name); gtfC (gene name); gtfD (gene name).
