Phenotypes of a mutant
60-fold increased mutation rate [Pubmed|23882084]a ''[gene|D5275ECDC2A70FBAC2CA5980F04B272C3328FC90|rnhB] [gene|E2A8B04CD729332F9E6A13195181983F751F2F25|mutS]-[gene|A86A013EDCE59D7EF84FB836A751E66C58CADF45|mutL]'' mutant is not viable [Pubmed|23882084]The protein
Catalyzed reaction/ biological activity
MutS recognizes mismatches in the DNA and recruits [protein|A86A013EDCE59D7EF84FB836A751E66C58CADF45|MutL] to the site of mismatch recognitionProtein family
