Effects of inhibition of proteoglycan synthesis on the differentiation of cultured rat Schwann cells.
J. Cell Biol. 105(2) , 1013-21, (1987) Schwann cells synthesize two heparan sulfate proteoglycans, one that is a component of the Schwann cell basement membrane and a smaller one that is an integral component of the Schwann cell plasma membrane. To determine the functions of these molecules, Schwa... |

Tetraisopropyldisiloxane-1,3-diyl as a versatile protecting group for pentopyranosides.
Carbohydr. Res. 353 , 92-5, (2012) The protecting group tetraisopropyldisiloxane-1,3-yl has been investigated for simultaneous protection of two hydroxyls on pentopyranosides. Methyl α-D-xylopyranoside is protected in excellent regioselectivity and high yield to form the 2,3-protected xylopyra... |

Transacetylations to carbohydrates catalyzed by acetylxylan esterase in the presence of organic solvent.
Biochim. Biophys. Acta 1623 , 62-71, (2003) Various conditions were applied to test the ability of acetylxylan esterase (AcXE) from Schizophyllum commune to catalyze acetyl group transfer to methyl beta-D-xylopyranoside (Me-beta-Xylp) and other carbohydrates. The best performance of the enzyme was obse... |

Synthesis of acylated methyl beta-D-xylopyranosides and their enzymic deacylations by rabbit serum esterases.
Carbohydr. Res. 302(1-2) , 13-8, (1997) Selective pivaloylations of methyl beta-D-xylopyranoside have been studied under various reaction conditions. Partially pivaloylated products were submitted to additional acetylations. The structures were established by 1H NMR spectroscopy. Representatives of... |

Determination of sugar structures in solution from residual dipolar coupling constants: methodology and application to methyl beta-D-xylopyranoside.
J. Am. Chem. Soc. 126(40) , 13100-10, (2004) We have developed methodology for the determination of solution structures of small molecules from residual dipolar coupling constants measured in dilute liquid crystals. The power of the new technique is demonstrated by the determination of the structure of ... |

Mode of action of acetylxylan esterase from Streptomyces lividans: a study with deoxy and deoxy-fluoro analogues of acetylated methyl beta-D-xylopyranoside.
Biochim. Biophys. Acta 1622(2) , 82-8, (2003) Streptomyces lividans acetylxylan esterase removes the 2- or 3-O-acetyl groups from methyl 2,4-di-O-acetyl- and 3,4-di-O-acetyl beta-D-xylopyranoside. When the free hydroxyl group was replaced with a hydrogen or fluorine, the rate of deacetylation was markedl... |

Extracellular matrix proteoglycans and cell-substratum adhesion of human endothelial cells: the effect of methyl beta-D-xylopyranoside.
Carbohydr. Res. 151 , 121-34, (1986) The influence of methyl beta-D-xylopyranoside on human endothelial cell proteoglycans isolated from the medium and extracellular matrix was investigated. Confluent cultures of human endothelial cells incorporate significant amounts of heparan sulfate (78%), c... |

Effect of tunicamycin on xylanase secretion in the yeast Cryptococcus albidus.
Arch. Biochem. Biophys. 265(1) , 183-9, (1988) The yeast Cryptococcus albidus secretes a glycosylated xylanase (48 kDa) in the culture medium in response to beta-methylxyloside as inducer. Addition of tunicamycin to the medium results in the formation of a modified xylanase (40 kDa) which is depleted in c... |

Deoxy and deoxyfluoro analogues of acetylated methyl beta-D-xylopyranoside--substrates for acetylxylan esterases.
Carbohydr. Res. 339(12) , 2101-10, (2004) Four modified substrates for acetylxylan esterases, 2-deoxy, 3-deoxy, 2-deoxy-2-fluoro, and 3-deoxy-3-fluoro derivatives of di-O-acetylated methyl beta-D-xylopyranoside were synthesized via 2,3-anhydropentopyranoside precursors. Methyl 2,3-anhydro-4-O-benzyl-... |
