title: Identification of two types of homologous DNA pairing activity in mouse cells.
abstract: We have identified two types of homologous DNA pairing activity in mouse cell extracts by a strand-transfer assay. Both activities are separated from each other by anion-exchange chromatography; neither of them needs ATP. One requires magnesium ion and is stimulated by Escherichia coli single-stranded DNA binding protein, whereas the other does not require the ion and shows a higher affinity for a left-handed Z-DNA.
