Mutator Gene Studies in Escherichia coli

Abstract

An Escherichia coli mutator gene, mutT, has been shown by P1-mediated crosses to map between the leucine and azide loci. The mutT1 and azi-r alleles cotransduce with a frequency of >92%. In mutT1/mutT+ merodiploids, the mutT1 phenotype is recessive; in mutT1/F′trp or mutT1/F′lac merodiploids, the mutT1 allele has a trans effect. The gene can mutate λ and T7 phage but not T1, T3, T4, T5, and S13.
