SECISearch3 and Seblastian: new tools for prediction of SECIS elements and selenoproteins [PDF]

open access: yes, 2014
Selenoproteins are proteins containing an uncommon amino acid selenocysteine (Sec). Sec is inserted by a specific translational machinery that recognizes a stem-loop structure, the SECIS element, at the 3′ UTR of selenoprotein genes and recodes a UGA ...

Effects of selenium biofortification on crop nutritional quality [PDF]

open access: yes, 2015
Selenium (Se) at very low doses has crucial functions in humans and animals. Since plants represent the main dietary source of this element, Se-containing crops may be used as a means to deliver Se to consumers (biofortification). Several strategies have

The effects of selenium on the translation efficiency of selenoproteins GPX1, GPX4, and TXNRD1 in oxLDL-induced EA.hy926 cells

open access: yesFood Science and Human Wellness
Selenium is a crucial trace element that contributes to physiological processes in the body as selenoproteins. Selenoproteins serve as an integral role in the body in controlling the redox state of cells and protecting against damage induced by oxidative

Modular Generation of Alkyl Selenyl Radicals for the Synthesis of Alkyl Selenides via a Mechanochemical Approach

open access: yesAdvanced Science, EarlyView.
We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...

The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]

open access: yes, 2014
Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

Prospects for the use of synthetic organoselenium compounds for the correction of metabolic and immune status during vaccination with live attenuated vaccines against especially dangerous infections

open access: yesActa Biomedica Scientifica, 2021
This review article analyzes the data on the role of selenium in the regulation of the metabolic and immune status of a macroorganism. The data on endogenousfunctional selenium-containing molecules, which include selenocysteine, selenomethionine, and ...

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

open access: yesAdvanced Science, EarlyView.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
