  • Title: [Comparative study of mutator-gene prv and several other mutator-genes of Escherichia coli K-12].
    Author: Khmel'nitskiĭ MI, Zlotnikov KM.
    Journal: Genetika; 1979; 15(5):823-30. PubMed ID: 378767.
    Abstract:
    Mutations prv1, prv2 and mutR34, increasing frequencies of intragenic recombinations, are found not to complement and therefore to be alleles of one gene. Checking for the influence of mutator genes mutS3, mutT1 and uvrE502 on the intragenic recombination in conjugational crossings has shown that mutators mutS3 and uvrE502 increase the frequency of intragenic recombinations while mutT1 does not change it. None of the examined mutator genes influence the conjugational frequencies of recombination. A supplementary analysis for the mutability of the mutant prv1 has been carried out. The prv1 mutation can induce mutations of the frameshift type. Mutations uvrA6, recB21, recC22 and lexA produce no influence on the display of a mutator effect of the prv1 mutation.
