metabolism
physiological function
-
fructan accumulation occurs mainly in the first 2 weeks after anthesis, and a maximal fructan concentration of 2.5 mg fructan per kernel is reached at 16 days after anthesis. Fructan synthesis is catalyzed by 1-SST (sucrose:sucrose 1-fructosyltransferase) and 6-SFT (sucrose:fructan 6-fructosyltransferase), and to a lesser extent by 1-FFT (fructan:fructan 1-fructosyltransferase). Despite the presence of 6G-kestotriose in wheat kernel extracts, the measured 6G-FFT (fructan:fructan 6G-fructosyltransferase) activity levels are low
additional information

the enzyme activity varies slightly during storage of fresh spears in the dark at 10°C for 14 days, while the sugar content is rapidly lost, overview
metabolism
the enzyme is required for fructan biosynthesis. In the second step, a 6G-FFT produces 6G-kestotriose, using 1-kestotriose as fructosyl donor and sucrose as fructosyl acceptor. In further steps, higher polymeric fructans are synthesized by a 1-FFT activity through beta(2-1)-linked chain elongation or by a 6-FT activity through beta(2-6)-linked chain elongation.The 6G-FFT from Lolium perenne also has 1-FFT activity
