Falsetta and colleagues [3] highlighted that poor oral hygiene and frequent consumption of sugars create bacterial adhesion to tooth surfaces via mineralization and biofilm formations caused by glucosyl and
fructosyl transferases.
Authors have described the thermostability of
fructosyl transferase enzyme from Rhodotorula sp.
FOS are oligosaccharides of fructose containing a single glucose moiety in which
fructosyl units are bound at the [beta] (2[right arrow]1) position of a sucrose molecule (Yun, 1996).
LAB employs sucrase-type enzymes to convert sucrose into homopolysaccharides consisting of either glucosyl units (glucans) or
fructosyl units (fructans).
These glycated valines become the substrates for specific recombinant
fructosyl valine oxidase (FVO) enzyme, which is produced in Escherichia coli.

These compounds comprise a functional food group containing mixed [beta]-D-fructans with two to four [beta](2-1) linked
fructosyl units displaying a terminal [alpha]-D-glucose residue, as kestose, nystose, fructosylnystose, and fructofuranosylnystose, among others [3].
Transgenic perennial ryegrass overexpressing wheat
fructosyl transferase genes, will and wft2 under CaMV 35S promoter, showed increased tolerance to freezing on a cellular level and accumulated greater amount of fructan than nontransgenic plants (Hisano et al., 2004).
For the cases of sucrose, starch and egg albumin, the monomer-unit concentration was also 1.0 mM (virtual molecular weight of glucosyl and
fructosyl moieties taken as 162 and 110 for aminoacyl moieties).
Some plants naturally convert sucrose to fructan by the activity of the enzyme
fructosyl transferase.
Structurally, this inulin-type FOS are short-chain oligomers of monosaccharide units consisting 1-kestose (GF2), nystose (GF3) and fructofuranosyl nystose (GF4) in which
fructosyl units are bound by [beta](2 [right arrow] 1) position of sucrose with the last one linked to a terminal glucose moiety (Fig.
We describe a new enzymatic assay for measuring GHb in which Hb in the sample is digested with a specific protease to generate
fructosyl amino acid (Fig.
