Nucleic acid molecules which encode proteins having fructosyl transferase activity and methods for producing long-chain inulin Nucleic acid molecules are described encoding proteins with the enzymatic activity of a fructosyl transferase. These enzymes are fructosyl transferases (FFT). Moreover, vectors and host cells are described containing the nucleic acid molecules of the invention, in particular transformed plant cells, plant tissue and plants regenerable therefrom, which express the described FFT. Furthermore, methods for the production of long-chain inulin by using the described proteins, hosts, in particular the plant cells and/or FFT produced by them, are described.

As moléculas do ácido nucleic que codificam as proteínas que têm a atividade e os métodos do transferase do fructosyl para produzir as moléculas long-chain do ácido nucleic do inulin são descritas que codificam proteínas com a atividade enzymatic de um transferase do fructosyl. Estes enzymes são os transferases do fructosyl (FFT). Além disso, os vetores e as pilhas de anfitrião são descritos que contêm as moléculas do ácido nucleic da invenção, nas pilhas da planta, no tecido de planta particular e nas plantas transformados regenerable therefrom, que expressam o FFT descrito. Além disso, os métodos para a produção do inulin long-chain usando as proteínas descritas, anfitriões, no detalhe as pilhas da planta e/ou o FFT produzidos por elas, são descritos.
