Three different systems participate in L-cystine uptake in Bacillus subtilis.

Pierre Burguière et al.

Journal of bacteriology, 186(15), 4875-4884 (2004-07-21)

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

In vitro radioprotection studies of organoselenium compounds: differences between mono- and diselenides.

B Santhosh Kumar et al.

Radiation and environmental biophysics, 48(4), 379-384 (2009-09-17)

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

Nanoparticulate glutathione peroxidase mimics based on selenocystine-pullulan conjugates.

Mamoru Haratake et al.

Bioconjugate chemistry, 19(9), 1831-1839 (2008-08-19)

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

Selenocystine induces S-phase arrest and apoptosis in human breast adenocarcinoma MCF-7 cells by modulating ERK and Akt phosphorylation.

Tianfeng Chen et al.

Journal of agricultural and food chemistry, 56(22), 10574-10581 (2008-10-31)

Selenocystine (SeC) is a nutritionally available selenoamino acid with selective anticancer effects on a number of human cancer cell lines. The present study shows that SeC inhibited the proliferation of human breast adenocarcinoma MCF-7 cells in a time- and dose-dependent

Molecularly defined antibody conjugation through a selenocysteine interface.

Thomas Hofer et al.

Biochemistry, 48(50), 12047-12057 (2009-11-10)

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
