Selenophosphate as a substrate for mammalian selenocysteine synthase, its stability and toxicity
The mechanism of selenocysteine synthesis on tRNASec in mammals was previously studied by means of HSe− as a Se donor to synthesize selenocysteine. It has been recently established that HSe− in E.Expand

The dual identities of mammalian tRNASec for SerRS and selenocysteine synthase
Se is an essential trace element and is found as a selenocysteine in the active site of Se-enzymes, such as glutathione peroxidase. tRNASec is first aminoacylated with serine by Ser RS and further isExpand

Map of Selenium Content in Soil in Japan
We present a new selenium (Se) map of Japan in more detail than in our previous report (J. Health Sci., 42, 360-366). It contains 150 measured points, especially in the northeast of Japan. In the newExpand

Trace 5-Methylaminomethyl-2-selenouridine in bovine tRNA and the selenouridine synthase activity in bovine liver
We measured the amount of Se in bovine liver tRNA. tRNA was chromatographed on a BD-cellulose column and Se-rich tRNA was eluted from the column in front of a main tRNA peak. There was 0.3 mmolExpand

Preliminary investigation of tRNA modification enzymes with Se in bovine liver.
We measured the amount of Se in the tRNA fractions eluted from a BD-cellulose column. Se was found in the fraction eluted early from the column as to be 3 x 10(-4) mol/mol of tRNA. This low amountExpand

Magnetic and structural properties of pseudo-binary compounds CrAs1−xPx
Abstract Structural and magnetic properties of pseudo-binary compounds CrAs 1− x P x (0≦ x ≦1) with the MnP-type structure have been studied by X-ray diffraction, magnetic susceptibilityExpand

Correlation of light transmittance with asthma attack: fine water particles as a possible inducing factor of asthma
Background and objectivesIt has been postulated that air-borne fine water particles (or mist) can induce asthma attacks in asthmatic children. To date, no attempt has been made to quantify theExpand

Active bovine selenophosphate synthetase 2, not having selenocysteine
During the course of studying selenocysteine (Sec) synthesis mechanisms in mammals, we prepared selenophosphate synthetase (SPS) from bovine liver by 4-step chromatography. In the last step ofExpand
