A DNA recombining protein has been partly purified from cell lines derived from patients suffering from the hereditary disease, Bloom's syndrome. The protein induces the formation of displacement loops in øX174 RFI DNA molecules after the addition of singlestranded DNA fragments. A filter binding method and electron microscopy were used to determine the reaction. The recombinogenic protein is dependent on divalent cations and ATP for activity.
