Utilization and metabolism of [U-14C]4' galactosyllactose (O-beta-D-galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl-(1----4)- D-glucopyranose) in rats.

O-beta-D-Galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl- (1----4)-D-glucopyranose (designated as 4'GL) are produced from lactose with Cryptococcus laurentii OKN-4. Excretion and metabolism of 4'GL in rats were examined using a radioisotope technique. [U-14c]4'GL was synthesized from [U-14C]lactose by Cryptococcus laurentii OKN-4. The 14CO2 in expired air was counted after oral administrati...

Improved Synthesis of 1-O-Acyl-β-d-Glucopyranose Tetraacetates.

An improved synthesis of 1-O-acyl glucosyl esters that avoids the use of expensive Ag reagents as well as the hydrolysis of unstable glucosyl bromides is reported. Notably, β-configuration products were obtained exclusively in good yields.

The 5-O-/3-D-Galactofuranosyl-containing Glycopeptide from Penicillium charlesii

Natural abundance carbon 13 nuclear magnetic resonance spectroscopy was used to confirm and extend the structural properties of peptidophosphogalactomannan (pPGM) from Penicillium charlesii. The major resonances for phosphogalactomannan (PGM) and phosphomannan (PM) were assigned. Based on comparison of chemical shifts of carbon 13 resonance signals in phosphogalactomannan with those of galactoc...

Aldolase-catalyzed synthesis of beta-D-galp-(1-->9)-D-KDN: a novel acceptor for sialyltransferases.

[reaction: see text] beta-D-Galp-(1-->9)-D-KDN, a disaccharide component of the cell wall of Streptomyces sp. MB-8, was synthesized from beta-D-Galp-(1-->6)-D-Manp and pyruvate using a sialic acid aldolase. The obtained KDN-containing compound was a novel acceptor for bacterial sialyltransferases. Unusual alpha2,3- and alpha2,6-linked sialyltrisaccharides and a tetrasaccharide were synthesized ...

The versatile enzyme Araf51 allowed efficient synthesis of rare pathogen-related β-D-galactofuranosyl-pyranoside disaccharides.

The preparation of galactofuranosyl-containing disaccharidic parts of natural glycoconjugates was performed according to a chemo-enzymatic synthesis. Our goals were firstly to develop an alternative approach to standard chemical strategies by limiting the number of reaction and purification steps, and secondly to evaluate the scope of the Araf51 biocatalyst to transfer a galactofuranosyl moiety...
