DNA‐dependent ATPase B of FM3A cells

Abstract
One form of DNA‐dependent ATPase (DNA‐dependent ATPase B) has been purified from FM3A cells. In this report, we describe the association of DNA polymerase α activity with DNA‐dependent ATPase B through a series of purification steps and the final separation of the two enzymes by glycerol gradient centrifugation operated at a low salt concentration.
