Kinetic properties of electrogenic Na+/H+ antiport in membrane vesicles from an alkalophilic Bacillus sp.
The effects of imposed proton motive force on the kinetic properties of the alkalophilic Bacillus sp. strain N-6 Na+/H+ antiport system have been studied by looking at the effect of delta psi (membrane potential, interior negative) and/or delta pH (proton gradient, interior alkaline) on Na+ efflux or H+ influx in right-side-out membrane vesicles. Imposed delta psi increased the Na+ efflux rate ...
متن کاملCaMKII-dependent regulation of cardiac Na+ homeostasis
Na(+) homeostasis is a key regulator of cardiac excitation and contraction. The cardiac voltage-gated Na(+) channel, NaV1.5, critically controls cell excitability, and altered channel gating has been implicated in both inherited and acquired arrhythmias. Ca(2) (+)/calmodulin-dependent protein kinase II (CaMKII), a serine/threonine kinase important in cardiac physiology and disease, phosphorylat...
متن کاملThe role of monovalent cation/proton antiporters in Na(+)-resistance and pH homeostasis in Bacillus: an alkaliphile versus a neutralophile.
Both neutralophilic Bacillus subtilis and alkaliphilic Bacillus firmus OF4 depend upon electrogenic Na+/H+ antiporters, which are energized by the gradients established by respiration-coupled proton extrusion, to achieve Na(+)-resistance and pH homeostasis when the external pH is very alkaline. The interplay of proton and sodium cycles is discussed. In B. subtilis, pH homeostasis, up to pH9, ca...
متن کاملThe voltage-gated Na+ channel NaVBP has a role in motility, chemotaxis, and pH homeostasis of an alkaliphilic Bacillus.
The prokaryotic voltage-gated Na(+) channel, NaChBac, is one of a growing channel superfamily of unknown function. Here we show that Na(V)BP, the NaChBac homologue encoded by ncbA in alkaliphilic Bacillus pseudofirmus OF4, is a voltage-gated Na(+) channel potentiated by alkaline pH. Na(V)BP has roles in motility, chemotaxis, and pH homeostasis at high pH. Reduced motility of bacteria lacking fu...
متن کاملBioenergetic properties and viability of alkalophilic Bacillus firmus RAB as a function of pH and Na+ contents of the incubation medium.
The bioenergetic properties and viability of obligately alkalophilic Bacillus firmus RAB have been examined upon incubation in alkaline and neutral buffers in the presence or absence of added Na+. At pH 10.5, cells incubated in the absence of Na+ exhibited an immediate rise in cytoplasmic pH from less than 9.5 to 10.5, and they lost viability very rapidly. Viability experiments in the presence ...
