A substrate ambiguous enzyme facilitates genome reduction in an intracellular symbiont.
BMC Biol. 12 , 110, (2015) Genome evolution in intracellular microbial symbionts is characterized by gene loss, generating some of the smallest and most gene-poor genomes known. As a result of gene loss these genomes commonly contain metabolic pathways that are fragmented relative to t... |

Protein enrichment of an Opuntia ficus-indica cladode hydrolysate by cultivation of Candida utilis and Kluyveromyces marxianus.
J. Sci. Food Agric. 95(5) , 1094-102, (2015) The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utili... |

Tissue vitamin concentrations are maintained constant by changing the urinary excretion rate of vitamins in rats' restricted food intake.
Biosci. Biotechnol. Biochem. 78(12) , 2102-9, (2014) We previously reported that mild food restriction induces a reduction in tryptophan-nicotinamide conversion, which helps to explain why death secondary to pellagra is pandemic during the hungry season. In this study, we investigated the levels of B-group vita... |

Metabolism of propionic acid to a novel acyl-coenzyme A thioester by mammalian cell lines and platelets.
J. Lipid Res. 56(1) , 142-50, (2014) Metabolism of propionate involves the activated acyl-thioester propionyl-CoA intermediate. We employed LC-MS/MS, LC-selected reaction monitoring/MS, and LC-high-resolution MS to investigate metabolism of propionate to acyl-CoA intermediates. We discovered tha... |

Stable isotope dilution liquid chromatography/mass spectrometry analysis of cellular and tissue medium- and long-chain acyl-coenzyme A thioesters.
Rapid Commun. Mass Spectrom. 28(16) , 1840-8, (2015) Acyl-Coenzyme A (CoA) thioesters are the principal form of activated carboxylates in cells and tissues. They are employed as acyl carriers that facilitate the transfer of acyl groups to lipids and proteins. Quantification of medium- and long-chain acyl-CoAs r... |

A multicopper oxidase contributes to the copper tolerance of Brucella melitensis 16M.
FEMS Microbiol. Lett. 362 , fnv078, (2015) Copper is a potent antimicrobial agent. Multiple mechanisms of copper tolerance are utilized by some pathogenic bacteria. BMEII0580, which is significantly similar to the multicopper oxidase from Escherichia coli, was predicted to be the probable blue copper ... |

Exercise and a High Fat Diet Synergistically Increase the Pantothenic Acid Requirement in Rats.
J. Nutr. Sci. Vitaminol. 61 , 215-21, (2015) It is thought that both exercise and dietary composition increase the utilization of, and thus the requirement for, certain water-soluble vitamins. However, there have been no studies evaluating the combined impacts of exercise and dietary composition on vita... |

bHLH05 is an interaction partner of MYB51 and a novel regulator of glucosinolate biosynthesis in Arabidopsis.
Plant Physiol. 166(1) , 349-69, (2014) By means of yeast (Saccharomyces cerevisiae) two-hybrid screening, we identified basic helix-loop-helix transcription factor05 (bHLH05) as an interacting partner of MYB51, the key regulator of indolic glucosinolates (GSLs) in Arabidopsis (Arabidopsis thaliana... |

Simultaneous quantification of 21 water soluble vitamin circulating forms in human plasma by liquid chromatography-mass spectrometry.
J. Chromatogr. A. 1422 , 89-98, (2015) This manuscript reports a validated analytical approach for the quantification of 21 water soluble vitamins and their main circulating forms in human plasma. Isotope dilution-based sample preparation consisted of protein precipitation using acidic methanol en... |
