T7 single strand DNA binding protein but not T7 helicase is required for DNA double strand break repair.

Abstract excerpt

An in vitro system based on Escherichia coli infected with bacteriophage T7 was used to test for involvement of host and phage recombination proteins in the repair of double strand breaks in the T7 genome. Double strand breaks were placed in a unique XhoI site located approximately 17% from the left end of the T7 genome. In one assay, repair of these breaks was followed by packaging DNA recovered from repair...
