Levansucrases of a Pseudomonas syringae pathovar as catalysts for the synthesis of potentially prebiotic oligo- and polysaccharides

- Inulin and inulin-type fructooligosaccharides from plants are prebiotic.
- Fructans with β-2,6 linkage have a potential as novel and effective prebiotics.
- Levansucrases from pseudomonads produce fructooligosaccharides and polymeric levan.
- Levansucrase Lsc3 is stable and efficient catalyst for fructan synthesis.
- Structure-function studies of Lsc3 have revealed catalysis-related positions.
