We isolated strains of Escherichia coli K 12 in which the lac structural genes were fused to the structural genes of the guaBA operon. These strains were used to isolate regulatory mutations that increased the expression of the guaBA operon under normal repressing conditions as compared to the wild

cur-l, a mutation found in many strains of the Y10 line of Escherichia coli K-12, but not previously described, maps at 27 rain, close to galU. cur-1 causes mucoidity or uracil requirement at 29 Β° C depending on the genetic background. These phenotypes are suppressed by amber codon suppressors.

To identify the nature and origin of spontaneous mutability we developed a screening procedure suitable to isolate antimutators showing a lower error rate than 10-10 per base per replication. Among about 500,000 mutagenized colonies we found 20 mutants showing a reduced spontaneous mutability. These

Exploitation of the ability of the ban protein encoded by phage P1 to compensate for dnaB-defective host mutations, allowed the isolation of dnaB: :Tnl0 insertion mutations. The presence of Plbac prophage was required for survival of dnaB::TnlO mutants, and such lysogens were cryosensitive. The inse

Taking advantage of the Spi (sensitivity to P2 interference) phenomenon, bacterial mutants seemingly resistant to phage lambdasusNnin5, but sensitive to phage lambdaspi, were isolated from a strain of E. coli K12 carrying no nonsense suppressor and lysogenic for P2. A class of these mutants, designa
