Substrates specialization in lipid compounds and hydrocarbons of Marinobacter genus.
Environ. Sci. Pollut. Res. Int. 22 , 15347-59, (2015) The impact of petroleum contamination and of burrowing macrofauna on abundances of Marinobacter and denitrifiers was tested in marine sediment mesocoms after 3 months incubation. Quantification of this genus by qPCR with a new primer set showed that the main ... |

Directed divergent evolution of a thermostable D-tagatose epimerase towards improved activity for two hexose substrates.
ChemBioChem. 16(4) , 592-601, (2015) Functional promiscuity of enzymes can often be harnessed as the starting point for the directed evolution of novel biocatalysts. Here we describe the divergent morphing of an engineered thermostable variant (Var8) of a promiscuous D-tagatose epimerase (DTE) i... |

A comprehensive HPLC analytical system for the identification and quantification of hexoses that employs 2-aminobenzamide coupling.
J. Biochem. 147(4) , 501-9, (2010) Rare sugars are defined as monosaccharides with extremely low natural abundances. Their natural distributions and biological functions remain to be clarified. To establish a robust analytical system that can separate, identify and quantify rare sugars, 12 d-h... |

The development of a new analytical model for the identification of saccharide binders in paint samples.
PLoS ONE 7 , e49383, (2012) This paper describes a method for reliably identifying saccharide materials in paintings. Since the 3(rd) millennium B.C., polysaccharide materials such as plant gums, sugar, flour, and honey were used as binding media and sizing agents in paintings, illumina... |

Analysis of plant gums and saccharide materials in paint samples: comparison of GC-MS analytical procedures and databases.
Chem. Cent. J. 6 , 115, (2013) Saccharide materials have been used for centuries as binding media, to paint, write and illuminate manuscripts and to apply metallic leaf decorations. Although the technical literature often reports on the use of plant gums as binders, actually several other ... |

Study on the postprandial blood glucose suppression effect of D-psicose in borderline diabetes and the safety of long-term ingestion by normal human subjects.
Biosci. Biotechnol. Biochem. 74(3) , 510-9, (2010) This clinical study was conducted to investigate the safety and effect of D-psicose on postprandial blood glucose levels in adult men and women, including borderline diabetes patients. A randomized double-blind placebo-controlled crossover experiment of singl... |

Improvement in the thermostability of D-psicose 3-epimerase from Agrobacterium tumefaciens by random and site-directed mutagenesis.
Appl. Environ. Microbiol. 77(20) , 7316-20, (2011) The S213C, I33L, and I33L S213C variants of D-psicose 3-epimerase from Agrobacterium tumefaciens, which were obtained by random and site-directed mutagenesis, displayed increases of 2.5, 5, and 7.5°C in the temperature for maximal enzyme activity, increases o... |

Failure of d-psicose absorbed in the small intestine to metabolize into energy and its low large intestinal fermentability in humans.
Metab. Clin. Exp. 59(2) , 206-14, (2010) Experiments with rats have produced data on the metabolism and energy value of d-psicose; however, no such data have been obtained in humans. The authors assessed the availability of d-psicose absorbed in the small intestine by measuring carbohydrate energy e... |

Rare sugar D-psicose improves insulin sensitivity and glucose tolerance in type 2 diabetes Otsuka Long-Evans Tokushima Fatty (OLETF) rats.
Biochem. Biophys. Res. Commun. 405(1) , 7-12, (2011) A rare sugar, D-psicose has progressively been evaluated as a unique metabolic regulator of glucose and lipid metabolism, and thus represents a promising compound for the treatment of type 2 diabetes mellitus (T2DM). The present study was undertaken to examin... |

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... |
