• Retinoic acid enhances Foxp3 induction indirectly by relieving inhibition from CD4+CD44hi Cells.

  CD4(+)Foxp3(+) regulatory T (Treg) cells originate primarily from thymic differentiation, but conversion of mature T lymphocytes to Foxp3 positivity c…

• Genetic evidence for an essential oscillation of transmembrane-spanning segment 5 in the Escherichia coli ammonium channel AmtB.

  Ammonium channels, called Amt or Mep, concentrate NH(4)(+) against a gradient. Each monomer of the trimer has a pore through which substrate passes an…

• Epistatic effects of the protease/chaperone HflB on some damaged forms of the Escherichia coli ammonium channel AmtB.

  The Escherichia coli ammonium channel AmtB is a trimer in which each monomer carries a pore for substrate conduction and a cytoplasmic C-terminal exte…

• Pyridoxal 5-phosphate inhibition of substrate selectivity mutants of UhpT, the sugar 6-phosphate carrier of Escherichia coli.

  In the sugar phosphate transporter UhpT, gain-of-function derivatives that prefer phosphoenolpyruvate (PEP) as substrate have an uncompensated lysine …
