Evidence: Keyed to Courses Using Broun, Mosteller, and ... - Pagina 94
Semet (P) sought to introduce testimony and photographs regarding a ladder from which he fell though neither his witness nor other evidence could establish that the ladder examined and photographed was the same one as was involved in ...

Protein Crystallization - Pagina 138
Selenium (Se) atoms are very good anomalous scatterers of X-rays. Se can be incorporated into proteins by replacing the methionines with selenomethionine (SeMet) during protein expression. The method provides a straightforward strategy ...

Functional Foods and Nutraceuticals in Cancer Prevention - Pagina 70
However, these forms of Se are not found in nature and the amounts needed are well beyond physiological intakes (El-Bayoumy et al. 1992, ElBayoumy et al. 1993, El-Bayoumy et al. 1995). 5. Other Mechanisms That the effects of SeMet on ...

Direct Methods for Solving Macromolecular Structures - Pagina 221
Special precautions must be taken to prevent oxidation of SeMet proteins. In almost all cases, somewhat higher-than-normal concentrations of disulfide reducing agents, such as dithiothreitol or 3-mercaptoethanol, are sufficient to protect ...

Quantitative Proteomics: - Pagina 119
L-SeMet is incorporated in place of L-Met in relation to the availability of L-SeMet in the pool of free amino acids. These L-SeMet-containing proteins can readily be detected, but not quantified by ICP-MS because, under normal circumstances, ...

2004) have reported quantitative SeMet concentrations in yeast after applying an enzymatic hydrolysis method based on protease XIV (200 mg, 37°C, 72 hr; or 400 mg, 37°C, 24 hr). SeMet levels found using enzymatic hydrolysis were ...

Selenium: Chemistry, Analysis, Function and Effects - Pagina 358
SeMet participates in three metabolic pathways. SeMet mimics Met and shares metabolic pathways with Met. First, SeMet is used for peptide synthesis in place of Met because the translation machinery of animals cannot distinguish SeMet ...

Environmental Chemistry of Selenium - Pagina 68
Abrams and Burau (1989) and Rael and Frankenberger (1995) have presented unequivocal mass spectrum data proving that the Se- containing amino acid selenomethionine (SeMet) is present in seleniferous soils and sediments. The origin ...

Trace Elements in Man and Animals 6 - Pagina 9
Interestingly, the glutathione peroxidase (GPX) activity did not differ significantly between tissues from rats fed SeMet versus selenite even though the Se content varied markedly.” This is an example where GPx activity is not always correlated ...
