An assay for thiaminase I in complex biological samples.
نویسندگان
چکیده
An alternative method for measuring thiaminase I activity in complex samples is described. This assay is based on the selective consumption of the highly chromophoric 4-nitrothiophenolate by thiaminase I, resulting in a large decrease in absorbance at 411nm. This new assay is simple and sensitive, and it requires only readily available chemicals and a visible region spectrophotometer. In addition, the assay is optimized for high-throughput analysis in a 96-well format with complex biological samples.

A Rapid Method for Assaying Thiaminase I Activity in Diverse Biological Samples
Vitamin B1 (thiamine) deficiencies can lead to neurological disorders, reproductive failure and death in wild and domestic animal populations. In some cases, disease is brought about by the consumption of foods high in thiaminase I activity. Levels of thiaminase activity in these foods are highly variable and the factors leading to production of this enzyme are poorly understood. Here we descri...
متن کاملStructure of a eukaryotic thiaminase I.
Thiaminases, enzymes that cleave vitamin B1, are sporadically distributed among prokaryotes and eukaryotes. Thiaminase I enzymes catalyze the elimination of the thiazole ring moiety from thiamin through substitution of the methylene group with a nitrogenous base or sulfhydryl compound. In eukaryotic organisms, these enzymes are reported to have much higher molecular weights than their bacterial...

A widely used procedure for site localization of covalent protein modifications involves proteolysis, partial chromatographic separation of the resulting complex mixture, and tandem mass spectrometry (MS/MS) to identify peptides whose molecular weight (Mr) has been increased appropriately by the modification. As found previously for MS of small molecules, this study shows that protein fragment ...

Dietary thiaminase I is a cause of thiamine deficiency in animals. The physiological significance of thiaminase in the organisms containing this enzyme is not known, nor are the factors causing variation in their thiaminase activity. Tests were performed to evaluate the effect a pathogen might have on thiaminase activity in fish, when analyzed both with a cosubstrate added (CATA tests) and no c...
