... and requires V-ATPase activity; (4) the Na + /H + antiporter is not involved in pH i recovery after a NH 4 Cl prepulse; and (5) at least one Na + -dependent transporter and the V-ATPase maintain recovery from an intracellular acid load. Thus, under resting conditions, the V-ATPase and at least one Na...

Shearer; Wen-Shu Wu ABSTRACT Gill epithelial cells of euryhaline crustaceans demonstrate net inward transport of sodium ions, possibly via apical Na + /H + antiporters, Na...

... β -adrenoceptors Na + /H + antiporter rainbow trout. In response to severe acute stress, many teleost fish, including the rainbow trout (Oncorhynchus mykiss), release the catecholamine hormones adrenaline and noradrenaline into their circulation (reviewed by Randall and Perry, 1992...

...Terry Ann Krulwich; Jianbo Cheng; Arthur A. Guffanti ABSTRACT 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...
