Recombination-promoting activity of the bacteriophage lambda Rap protein in Escherichia coli K-12.

Abstract excerpt

The rap gene of bacteriophage lambda was placed in the chromosome of an Escherichia coli K-12 strain in which the recBCD gene cluster had previously been replaced by the lambda red genes and in which the recG gene had been deleted. Recombination between linear double-stranded DNA molecules and the chromosome was tested in variants of the recGDelta red(+) rap(+) strain bearing mutations in genes known to affect...
