Amilorides, well-known inhibitors of Na(+)/H(+) antiporters, have also shown to inhibit bacterial and mitochondrial NADH-quinone oxidoreductase (complex I). Since the membrane subunits ND2, ND4, and ND5 of bovine mitochondrial complex I are homologous to Na(+)/H(+) antiporters, amilorides have been thought to bind to any or all of the antiporter-like subunits; however, there is no direct experimental
