Development of D-allose sensor on the basis of three strategic enzyme reactions.
Biosens. Bioelectron. 26 , 126-30, (2010) Rare sugars are defined as monosaccharides and their derivatives that rarely exist in nature, according to the International Society of Rare Sugars. D-Allose (3-epi d-glucose) is one of the rare sugars, for which various physiological activities have recently... |

Characterization of a recombinant cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus and its application in the production of mannose from glucose.
Appl. Microbiol. Biotechnol. 92 , 1187-1196, (2011) A putative N-acyl-D-glucosamine 2-epimerase from Caldicellulosiruptor saccharolyticus was cloned and expressed in Escherichia coli. The recombinant enzyme was identified as a cellobiose 2-epimerase by the analysis of the activity for substrates, acid-hydrolyz... |

HPLC separation of all aldopentoses and aldohexoses on an anion-exchange stationary phase prepared from polystyrene-based copolymer and diamine: the effect of NaOH eluent concentration.
Molecules 16(7) , 5905-15, (2011) To investigate the separations of all aldopentoses (ribose, arabinose, xylose and lyxose) and aldohexoses (glucose, galactose, allose, altrose, mannose, gulose, idose and talose) on the D₆ stationary phase prepared by the reaction of chloromethylated styrene-... |

Direct evidence for the ring opening of monosaccharide anions in the gas phase: photodissociation of aldohexoses and aldohexoses derived from disaccharides using variable-wavelength infrared irradiation in the carbonyl stretch region.
Carbohydr. Res. 346(15) , 2469-81, (2011) All eight D-aldohexoses and aldohexoses derived from the non-reducing end of disaccharides were investigated by variable-wavelength infrared multiple-photon dissociation (IRMPD) as anions in the negative-ion mode. Spectroscopic evidence supports the existence... |

DFTMD studies of glucose and epimers: anomeric ratios, rotamer populations, and hydration energies.
Carbohydr. Res. 345(4) , 503-11, (2010) Results are presented from density functional molecular dynamics (DFTMD) simulations, based on constant energy dynamics, of glucose and its cyclic form of 6-carbon epimers. Both in vacuo and an implicit solvent method (COSMO) were examined, including simulati... |

D-Psicose induces upregulation of defense-related genes and resistance in rice against bacterial blight.
J. Plant Physiol. 168(15) , 1852-7, (2011) We examined rice responses to a rare sugar, d-psicose. Rice growth was inhibited by d-psicose but not by common sugars. Microarray analysis revealed that d-psicose treatment caused an upregulation of many defense-related genes in rice, and dose-dependent upre... |

Increased D-allose production by the R132E mutant of ribose-5-phosphate isomerase from Clostridium thermocellum.
Appl. Microbiol. Biotechnol. 89(6) , 1859-66, (2011) Ribose-5-phosphate isomerase from Clostridium thermocellum converted D-psicose to D-allose, which may be useful as a pharmaceutical compound, with no by-product. The 12 active-site residues, which were obtained by molecular modeling on the basis of the solved... |

D-allose and D-psicose reinforce the action of metronidazole on trichomonad.
Parasitol. Res. 110(4) , 1565-7, (2012) The effects of D-allose and D-psicose on Tritrichomonas foetus were examined. They were cultured in F-bouillon medium including glucose, but had never increased when glucose was substituted to those sugars. When cultured in a medium including a dose of ED(50)... |

Microbial metabolism and biotechnological production of D-allose.
Appl. Microbiol. Biotechnol. 91 , 229-35, (2011) D-allose has attracted a great deal of attention in recent years due to its many pharmaceutical activities, which include anti-cancer, anti-tumor, anti-inflammatory, anti-oxidative, anti-hypertensive, cryoprotective, and immunosuppressant activities. D-allose... |

Characterization of a thermophilic L-rhamnose isomerase from Thermoanaerobacterium saccharolyticum NTOU1.
J. Agric. Food Chem. 58(19) , 10431-6, (2010) L-rhamnose isomerase (EC 5.3.1.14, L-RhI) catalyzes the reversible aldose-ketose isomerization between L-rhamnose and L-rhamnulose. In this study, the L-Rhi gene encoding L-Rhi was PCR-cloned from Thermoanaerobacterium saccharolyticum NTOU1 and then expressed... |
