What is Structural characterization of the maltose acceptor-products synthesized by Leuconostoc mesenteroides NRRL B-1299 dextransucrase about?
The glucooligosaccharides (GOS), produced by Leuconostoc mesenteroides NRRL B-1299 dextransucrase through an acceptor reaction with maltose and sucrose, were purified by reverse phase chromatography. Logarithmic plots of retention time vs. dp of the GOS gave three parallel lines suggesting the existence of at least three families of homologous molecules. The structure (~3C and ~H NMR spectroscopy) and reactivity of the purified molecules of the three families were investigated. All the products bear a maltose residue at the reducing end. The GOS in the first family (named OD) contained additional glucosyl residues all c~-(1 ~ 6) linked. The smallest molecule in this first series was panose or Ce-D-glucopyranosyl-(1 ~ 6)-D-maltose (dp 3). All the OD molecules were shown to be good acceptors for dextransucrase in the presence of sucrose. The second family, named R, was composed of linear GOS containing c~-(1 ~ 6)-linked glucosyl residues and a terminal a-(l ~ 2)-linked residue at the non-reducing end of the molecule; the smallest molecule in this family was ce-D-glucopyranosyl-(1 ~ 2)-D-panose (dp 4). The third family, R', was formed of GOS containing additional residues linked throu
