title: DNA synthesis involving a complexes form of DNA polymerase I in extracts of Escherichia coli.
abstract: DNA polymerase I (EC 2.7.7.7; deoxynucleosidetriphosphate:DNA deoxynucleotidyltransferase) has been recovered as a complex of about 390,000 molecular weight. The complex displays an ATP-stimulated DNA-synthesizing activity that prefers native to heat-denatured DNA. Genetic evidence indicates that the recBC enzyme is associated with the polymerase in the complex. Preliminary evidence for complexes involving DNA polymerases II and III is also presented.
