F-prime heterogenotes of dam-3 bacteria segregate F-prime homogenotes at a frequency 30-200 times higher than the isogenic dam+ strain. A hyperrecombination mutant which shows increased recombination between chromosomal duplications was characterized as a dam mutant. The dam-3 allele causes a reduct

โฆ Synopsis
The dam gene of E. coli can be inactivated by insertion of Tn9 or Mud phage. Strains bearing these mutations are viable indicating that the dam gene product is dispensable.

The recQ gene of Escherichia coli K12 was subcloned from plasmid pKO1 (Oeda et al. 1981) by monitoring the capacity of the resulting recombinant plasmids partially to reverse the increased ultraviolet (UV) sensitivity of a reeF143 recQ1 double mutant. We were able to trace this complementation activ
It has previously been proposed, based on indirect evidence, that the Rho protein may control the expression of the rho gene. Using an in vitro system for the transcription and translation of the rho gene cloned into plasmid pBR322, we tested this hypothesis directly by monitoring the effect in vitr
The gene ompA encodes a major outer membrane protein of Escherichia coli. Localized mutagenesis of the part of the gene corresponding to the 21-residue signal sequence and the first 45 residues of the protein resulted in alterations which caused cell lysis when expressed.

Temperature-sensitive (ts) mutations were isolated within a ribosomal protein gene (rpsL) of Escherichia coli K12. Mutations were mapped by complementation using various transducing phages and plasmids carrying the rpsL gene, having either a normal or a defective promoter for the rpsL operon. One of
