comparative study of all major fructan-metabolizing enzymes together with fructan content, fructan degree of polymerization and the presence of fructan oligosaccharides in developing wheat kernels, overview. Fructan synthesis is catalyzed by sucrose:sucrose 1-fructosyltransferase, EC 2.4.1.99, and sucrose:fructan 6-fructosyltransferase, EC 2.4.1.10, and to a lesser extent by fructan:fructan 1-fructosyltransferase, EC 2.4.1.100 |

fructan-fructan 1-fructosyltransferase mediates linear beta(2->1) linkage elongation of 1-kestose and bifurcose to produce mixed levan |

| 2.4.1.100 | metabolism |
inulin synthesis is the result of the combined action of sucrose:sucrose 1-fructosyltransferase, 1-SST, EC 2.4.1.99, and fructan:fructan 1-fructosyltransferase, 1-FFT, where 1-SST catalyzes the formation of 1-kestotriose from two sucrose molecules, while releasing glucose. Secondly 1-FFT transfers fructosyl units from one inulin molecule to another to elongate the inulin chain |

| 2.4.1.100 | 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 |
