The symporter YhcL and two ATP binding cassette transporters, YtmJKLMN and YckKJI, were shown to mediate L-cystine uptake in Bacillus subtilis. A triple DeltayhcL DeltaytmJKLMN DeltayckK mutant was unable to grow in the presence of L-cystine and to take up

We synthesized nanoparticulate glutathione peroxidase (GPx) mimics in which selenocystine (SeCyst) was conjugated to a hydrophilic linear polysaccharide, pullulan (Pul). The SeCyst ester-conjugated Pul derivatives (SeCyst-Pul) in phosphate buffer (pH 7) were treated with a sonicator to spontaneously form particulate

Organoselenium compounds belonging to the class of monoselenides, such as selenomethionine (SeM) and methylselenocysteine (MSeCys) and diselenides including selenocystine (SeCys) and selenopropionic acid (SePA), were examined for their comparative radioprotective effects using in vitro models. Effects of these compounds on

The uptake of Se (VI) by two aquatic plants, Myriophyllum spicatum L. and Ceratophyllum demersum L., and its effects on their physiological characteristics have been studied. Plants were cultivated outdoors under semi-controlled conditions and in two concentrations of Na selenate

Antibody conjugates have broad utility in basic, preclinical, and clinical applications. Conventional antibody conjugation through the amine group of lysine or the thiol group of cysteine residues yields heterogeneous products of undefined stoichiometry and considerable batch-to-batch variability. To preserve the
