-
both 1-kestotriose and 6G-kestotriose acts as fructosyl acceptors, producing 1- and 6-kestotetraose (bifurcose) and 6G,6-kestotetraose, respectively. 1-Kestotriose is not a fructosyl donor since incubation with 1-kestotriose alone does not lead to the synthesis of a 6-linked fructan. Bifurcose formation ceases and 6G,6-kestotetraose is formed instead, when recombinant fructan:fructan 6G-fructosyltransferase, 6G-FFT, is introduced in the enzyme assay with sucrose and 1-kestotriose as substrates

6G-kestotriose is formed by enzyme 6G-FFT, transferring fructose from 1-kestotriose to sucrose, while the 6G-kestotriose levels formed in the assays with added 1-kestotriose and sucrose are rather small. Rapid chain elongation of 6G-kestotriose into 1+6G-kestotetraose and possibly other higher degree of polymerization fructans
