Substrates Comment Substrates Organism Products Comment (Products) Rev. Reac.
sucrose + (1,6-alpha-D-glucosyl)n dextransucrase preferentially produces an isomaltooligosaccharide series, whose concentration is always low because of the high ability of these products to be elongated and form high molecular weight dextran. In dextransucrase, the A repeats define anchoring zones for the growing chains, favoring their elongation. Based on these results, a semi-processive mechanism involving only one active site and an elongation by the non-reducing end is proposed Leuconostoc mesenteroides D-fructose + (1,6-alpha-D-glucosyl)n+1
