title: The MutS C terminus is essential for mismatch repair activity in vivo.
abstract: An Escherichia coli K-12 strain was constructed with a chromosomal deletion (mutSdelta800) in the mutS gene that produced the removal of the C-terminal 53 amino acids which are not present in the MutS crystal structure. This strain has a MutS null phenotype for mutation avoidance, anti-recombination, and sensitivity to cytotoxic agents in a dam mutant background.
