Described are nucleic acid molecules encoding enzymes having fructosyl polymerase activity. These enzymes are sucrose dependent sucrose fructosyltransferases (SST) enzymes. Furthermore, vectors and host cells are described containing the nucleic acid molecules, in particular transformed plant cells and plants that can be regenerated from them and that express the described SSTs. Furthermore, methods for the production of short-chain fructosyl polymers using the described hosts and/or the SSTs produced by them are described.
L'invention concerne des molécules d'acide nucléique codant des enzymes présentant une activité de fructosylpolymérase. Ces enzymes sont des enzymes fructosyltransférases de sacharose (SST) dépendantes de la sacharose. En outre, l'invention traite aussi de vecteurs et de cellules hôtes contenant les molécules d'acide nucléique, en particulier, des cellules de plantes transformées et des plantes qui peuvent être régénérées à partir de ces dernières et qui expriment les enzymes fructosyltransférases de sacharose décrites. En outre, l'invention a pour objet des procédés pour la production de polymères de fructosyle à chaîne courte, utilisant les hôtes décrits et/ou les enzymes SST ainsi produites.
