...Alex M. Zimmer; Khatereh Shir-Mohammadi; Raymond W. M. Kwong; Steve F. Perry ABSTRACT Freshwater fishes absorb Na + from their dilute environment using ion-transporting cells. In larval zebrafish ( Danio rerio ), Na + uptake is coordinated by (1) Na + /H + exchanger 3b (Nhe3b) and (2) H + -ATPase...

... transporters (Rhcg, V-type H + -ATPase, Na + /H + exchanger NHE-2 and/or NHE-3, Na + channel) working together as a metabolon provides an acid trapping mechanism for apical excretion. Intracellular carbonic anhydrase(CA-2) and basolateral Na + /HCO – 3 cotransporter (NBC-1) and Na + /K + -ATPase play indirect...

... with significant effects of ouabain, DMA, bafilomycin A 1 and DIDS on aerobic energy turnover strongly suggest that a Na + /K + -ATPase, a Na + /H + exchanger, an H + -ATPase and an anion exchanger operate in this tissue. Since application of DIDS delayed pH recovery from acidosis and induced an acidosis rather...

... cells. For the first time, the Na + /K + -ATPase and H + -ATPase activities of fish gills were determined in intact cells in situ . The activity of both ATPases was dependent on alamethicin concentration (optimum 100 μ g mg −1 protein) and on preincubation time (optimum 10 min). The in situ activity...
