2-Aminoperimidine, a specific inhibitor of bacterial NhaA Na+/H+ antiporters [PDF]
FEBS Letters, 2005 The diuretic drug amiloride and its numerous derivatives are competitive inhibitors of mammalian Na+/H+ antiporters and other eukaryotic antiporters. Most prokaryotic antiporters, including the major NhaA family of enterobacteria, are resistant to these ...

Enantioselective Antiport in Asymmetric Nanochannels
ACS Nano, 2021Enantioselective sensing and separation are major challenges. Nanochannel technologies are energy-saving and efficient for membrane separation. Herein, inspired by biological antiporter proteins, artificial nanochannels with antiporter behavior were fabricated for chiral sensing and separation.

Uniporters and anion antiporters
Current Opinion in Cell Biology, 1991The past year has seen a flurry of activity in the area of protein-mediated hexose uniport. Topics of interest covered here include: structure-function studies; the interaction of glucose carriers with glycolytic enzymes; regulation of cell surface glucose-carrier concentrations by insulin and the signalling mechanisms involved; and the role of the ...

K+/H+ antiport in mitochondria
Journal of Bioenergetics and Biomembranes, 1988Mitochondria contain a latent K+/H+ antiporter that is activated by Mg2+-depletion and shows optimal activity in alkaline, hypotonic suspending media. This K+/H+ antiport activity appears responsible for a respiration-dependent extrusion of endogenous K+, for passive swelling in K+ acetate and other media, for a passive exchange of matrix 42K+ against ...

Cation/proton antiport systems in Escherichia coli: Properties of the sodium/proton antiporter
Archives of Biochemistry and Biophysics, 1979Abstract The sodium/proton antiport system of Escherichia coli has been characterized by the effect of Na+ on the pH gradient established by respiration in everted membrane vesicles. The system has equal affinity for Na+ and Li+. Between pH 7 and 9 dissipation of Δψ, membrane potential, has no effect on the affinity for Na+ but decreases the V of the

Uniporters, Symporters and Antiporters
Journal of Experimental Biology, 1994ABSTRACT Transporters are a diverse group of membrane proteins that facilitate the movement of water-soluble solutes through the lipid bilayer of biological membranes. The least complex transporters are the uniporters (Kakuda and MacLeod, 1994).

Na+/H+ antiports or exchange reactions have been found widely, if not ubiquitously, in prokaryotic and eukaryotic membranes. In any given experimental system, the multiplicity of ion conductance pathways and the absence of specific inhibitors complicate efforts to establish that the antiport observed actually results from the activity of a specific ...
