Roasting-induced changes in arabinotriose, a model of coffee arabinogalactan side chains.
Food Chem. 138(4) , 2291-9, (2013) Thermal processing can promote reactions that change the structure of food constituents, often by unknown mechanisms, such as those occurring in arabinose residues of coffee arabinogalactan side chains. Aiming to know more about these modifications, the struc... |

Crystal structure of glycoside hydrolase family 127 β-l-arabinofuranosidase from Bifidobacterium longum.
Biochem. Biophys. Res. Commun. 447(1) , 32-7, (2014) Enzymes acting on β-linked arabinofuranosides have been unknown until recently, in spite of wide distribution of β-l-arabinofuranosyl oligosaccharides in plant cells. Recently, a β-l-arabinofuranosidase from the glycoside hydrolase family 127 (HypBA1) was dis... |

Mutualistic growth of the sulfate-reducer Desulfovibrio vulgaris Hildenborough with different carbohydrates.
Mikrobiologiia 81(6) , 720-5, (2012) Desulfovibrio vulgaris Hildenborough genome presents a phosphotransferase system putatively involved in the transport of carbohydrates. However, utilization of sugars by this sulfate-reducing bacterium has never been reported. Herein, we have observed prolife... |

Structural characteristics and antioxidant activities of polysaccharides from longan seed.
Carbohydr. Polym. 92(1) , 758-64, (2013) Ultrasound-assisted extraction was employed to extract polysaccharides from longan seed (LSP), with aids of a Box-Behnken statistical design to investigate the effects of ultrasonic power, time and liquid/solid ratio on the extraction recovery of the LSP. The... |

Role of bacterial surface structures on the interaction of Klebsiella pneumoniae with phagocytes.
PLoS ONE 8(2) , e56847, (2013) Phagocytosis is a key process of the immune system. The human pathogen Klebsiella pneumoniae is a well known example of a pathogen highly resistant to phagocytosis. A wealth of evidence demonstrates that the capsule polysaccharide (CPS) plays a crucial role i... |

Permeation of aldopentoses and nucleosides through fatty acid and phospholipid membranes: implications to the origins of life.
Astrobiology 13(2) , 177-88, (2013) Permeation of aldopentoses and nucleosides through fatty acid and phospholipid membranes was investigated by way of molecular dynamics simulations. Calculated permeability coefficients of membranes to aldopentoses, which exist predominantly in the pyranose fo... |

Positron emission tomography probe demonstrates a striking concentration of ribose salvage in the liver.
Proc. Natl. Acad. Sci. U. S. A. 111(28) , E2866-74, (2014) PET is a powerful technique for quantifying and visualizing biochemical pathways in vivo. Here, we develop and validate a novel PET probe, [(18)F]-2-deoxy-2-fluoroarabinose ([(18)F]DFA), for in vivo imaging of ribose salvage. DFA mimics ribose in vivo and acc... |

Enzymatic saccharification of sugar beet pulp for the production of galacturonic acid and arabinose; a study on the impact of the formation of recalcitrant oligosaccharides.
Bioresour. Technol. 128 , 518-25, (2013) Enzymatic saccharification of sugar beet pulp was optimized on kg-scale to release the maximum amounts of monomeric galacturonic acid and arabinose with limited concomitant degradation of cellulose, using conditions that are feasible for industrial upscaling.... |

[Utilization of carbon sources by Fusarium poae (Peck) Wollenw. Strains from different trophic groups].
Mikrobiol. Z. 75(1) , 54-68, (2013) It was shown that saprophytic (soil), endophytic and plant pathogenic strains of F. poae under cultivation conditions in the media containing carbon sources from mono- to polysaccharides had different abilities to use them and to accumulate biomass. Maltose, ... |

Evaluation of thermodynamic parameters of some amphiphilic drugs in presence of sugars at the cloud point.
Colloids Surf. B Biointerfaces 105 , 236-45, (2013) In the present investigation, we report the thermodynamics of clouding in four amphiphilic drugs viz., two tricyclic antidepressants: amitriptyline hydrochloride (AMT) and imipramine hydrochloride (IMP) and two phenothiazines: chlorpromazine hydrochloride (CP... |
