title: Identification of a second cryptic lambdoid prophage locus in the E. coli K12 chromosome.
abstract: In addition to the cryptic lambdoid prophage genes that are known to reside at the rac locus in Escherichia coli K12 strains, a second cryptic lambdoid prophage has been located near the gal operon. This prophage was shown to contain DNA that is homologous to the QSR genes of lambda phage.
