Sulfate permeasesphylogenetic diversity of sulfate transport.

Acta Biochimica Polonica, 2009
Sulfate uptake, the first step of sulfate assimilation in all organisms, is a highly endoergic, ATP requiring process. It is under tight control at the transcriptional level and is additionally modulated by posttranslational modifications, which are not yet fully characterized.

Thermochemistry, Structure, and Optical Properties of a New β-La₂(SO₄)₃ Polymorphic Modification

Inorganics, 2023
A new polymorphic modification of lanthanum sulfate was obtained by thermal dehydration of the respective nonahydrate. According to powder X-ray diffraction, it was established that β-La2(SO4)3 crystallized in the C2/c space group of the monoclinic ...

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

FEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...
