IN the course of studying ATP hydrolysis by the sodium pump, we have measured ouabain binding to ox brain microsomes. Our results on binding in the presence of Na, ATP and Mg agree with earlier findings, but our results with Mg alone lead us to question the validity of models which have been proposed for the mechanism of the sodium pump1–3.
