Characterization of Na+/Mg2+ antiport by simultaneous 28Mg2+ influx |pdf=|usr=}}{{3689385}} gab.com Text Characterization of Na+/Mg2+ antiport by simultaneous 28Mg2+ influx JO: Biochem Biophys Res Commun http://www.kidney.de/pget.php?&tw=1&pmid=3689385 #FOAvip During net Mg2+ efflux from Mg2+-preloaded chicken erythrocytes, which occurs via Na+/Mg2+ antiport, 28Mg2+ is taken up intracellularly. Km of 28Mg2+ influx amounted to 1 mM. In Na+-free medium Vmax of 28Mg2+ influx was increased and Km was reduced to 0.2 mM. 28Mg2+ influx was noncompetitively inhibited by amiloride as was found for Na+/Mg2+ antiport. The results indicate that, extracellularly, Mg2+ can compete with Na+ for common binding sites of the Na+/Mg2+ antiporter, resulting in 28Mg2+-24Mg2+ exchange. The rate of Mg2+ exchange depends on extracellular Na+ and on the rate of net Mg2+ efflux.
