Nucleotide sequence of the chi recombinational hot spot chi +D in bacteriophage lambda.
Chi sites in bacteriophage lambda stimulate recombination promoted by the RecBC pathway of Escherichia coli. Mutations which create these sites occur at four widely separated loci in lambda. We report here the nucleotide sequence surrounding the site of one of these loci, chi D, located near the S gene. The mutations creating the active Chi site, designated chi +D, are transversions from CG to AT. This mutation, like the chi +B and chi +C mutations previously analyzed, leads to a nucleotide sequence common to all three active chi sites.
