The genus Acinetobacter encompasses a heterogeneous group of bacteria that are
ubiquitous in the natural environment due in part to their ability to adapt genetically to novel …

In prokaryotic mismatch repair the MutS protein and its homologs recognize the mismatches.
The mutS gene of naturally transformable Pseudomonas stutzeri ATCC 17587 (genomovar …

DNA mismatch repair in Escherichia coli has been shown to be involved in two distinct
processes: mutation avoidance, which removes potential mutations arising as replication …

An Escherichia coli K-12 strain was constructed with a chromosomal deletion (mutS Δ 800)
in the mutS gene that produced the removal of the C-terminal 53 amino acids which are not …

We used the lacI system of Escherichia coli to examine the distribution of base substitution
mutations occurring spontaneously in different mismatch-repair-deficient strains. The …

The MutS protein of Escherichia coli is part of the dam-directed MutHLS mismatch repair
pathway which rectifies replication errors and which prevents recombination between …

We show that the MutY protein competes with the MutS-dependent mismatch repair system
to process at least some A· C mispairs in vivo, converting them to G· C pairs. In the presence …

The mismatch repair system is involved in the maintenance of genomic integrity by editing
DNA replication and recombination. However, although most mutations are neutral or …

We have used direct selections to generate large numbers of mutants of Escherichia coli
defective in the mismatch repair system and have screened these to identify mutants with …

The mutB gene of Salmonella typhimurium is involved in a methylation-independent repair
pathway specific for A/G or A/C mismatches and is the homolog of the Escherichia coli mutY …
