sucrose or raffinose act as substrates, both donor and acceptor of fructose moieties. Sucrose is the preferred substrate. The enzyme synthezises fructooligosaccharides from degree of polymerization of 3 (1-kestose) to 9, as well as minor amounts of neo-kestose and inulobiose, product analysis by NMR spectroscopy, overview. Synthezised oligomers are identified as alpha-D-galactopyranosyl-(1->6)-alpha-D-glucopyranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranoside, alpha-D-galactopyranosyl-(1->6)-alpha-D-glucopyranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranoside, alpha-D-galactopyranosyl-(1->6)-alpha-D-glucopyranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranoside, alpha-D-galactopyranosyl-(1->6)-alpha-D-glucopyranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranoside, and alpha-D-galactopyranosyl-(1->6)-alpha-D-glucopyranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranosyl-(1->2)-beta-D-fructofuranoside |
