Functional activation of G-proteins coupled with muscarinic acetylcholine receptors in rat brain membranes.
J. Pharmacol. Sci. 125(2) , 157-68, (2014) The functional activation of Gi/o proteins coupled to muscarinic acetylcholine receptors (mAChRs) was investigated with the conventional guanosine-5'-O-(3-[(35)S]thio) triphosphate ([(35)S]GTPγS) binding assay in rat brain membranes. The most efficacious stim... |

Salvage of the thiamin pyrimidine moiety by plant TenA proteins lacking an active-site cysteine.
Biochem. J. 463(1) , 145-55, (2014) The TenA protein family occurs in prokaryotes, plants and fungi; it has two subfamilies, one (TenA_C) having an active-site cysteine, the other (TenA_E) not. TenA_C proteins participate in thiamin salvage by hydrolysing the thiamin breakdown product amino-HMP... |

Determination of thiamine and its phosphate esters in rat tissues analyzed as thiochromes on a RP-amide C16 column.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 816(1-2) , 67-72, (2005) A new reversed-phase chromatographic method is described for the separation and quantification of thiamine (T), thiamine monophosphate (TMP) and diphosphate (TDP) in rat tissues. Sample extraction with perchloric acid (HClO(4)) was found more suitable than ex... |

Thiamine biosynthesis in Escherichia coli: in vitro reconstitution of the thiazole synthase activity.
J. Biol. Chem. 279(17) , 17054-62, (2004) The biosynthesis of thiamine in Escherichia coli requires the formation of an intermediate thiazole from tyrosine, 1-deoxy-d-xylulose-5-phosphate (Dxp), and cysteine using at least six structural proteins, ThiFSGH, IscS, and ThiI. We describe for the first ti... |

A reliable semiautomated method for the determination of total thiamine in whole blood by the thiochrome method with high-performance liquid chromatography.
Ann. Clin. Biochem. 19(Pt 1) , 52-6, (1982) A sensitive and reliable method for the determination of total thiamine (vitamin B1) in whole blood has been developed which is suited for routine analysis. After extraction, and enzymatic hydrolysis of thiamine phosphate esters, thiamine is separated from in... |

[Effect of thiochrome capronate on lipid metabolism in rats].
Ukr. Biokhim. Zh. 58(5) , 89-91, (1986) Thiochrome caproate modified by the oxyethyl radical of the thiochrome derivative was studied for its effect on different indices of lipid metabolism in the liver and blood of albino rats. It was shown that when animals were fed on a standard laboratory diet,... |

Determination of thiamine in pharmaceutical preparations by sequential injection renewable surface solid-phase spectrofluorometry.
Anal. Sci. 19(2) , 289-94, (2003) Fluorometric determination of thiamine requires the conversion of the analyte to fluorescent thiochrome by hexacyanoferrate(III) oxidation in alkaline solution and the isolation of the produced thiochrome from the reaction medium by solvent extraction. It was... |

The coenzyme thiamine pyrophosphate inhibits the self-splicing of the group I intron.
Int. J. Biochem. Cell Biol. 35(2) , 157-67, (2003) Effects of the coenzyme thiamine pyrophosphate and its analogs on the inhibition of self-splicing of primary transcripts of the phage T4 thymidylate synthase gene (td) were investigated. Of all compounds tested, the coenzyme thiamine pyrophosphate was the mos... |
