title: Adenosine triphosphatase and adenosine diphosphate/adenosine triphosphate isotope-exchange activities of the chromaffin-granule membrane.
abstract: The association of adenosine triphosphatase and ADP/ATP isotope-exchange activities with chromaffin-granule membranes was shown by sucrose-density-gradient centrifugation. The two activities were solubilized, and separated by differential sedimentation.
