  • Title: Altered regulation of the recA gene in Escherichia coli strains carrying a recA-linked suppressor of lexA.
    Author: Thomas A, Lloyd RG.
    Journal: Mol Gen Genet; 1980; 179(2):355-8. PubMed ID: 7007810.
    Abstract:
    A mutant strain of E. coli displaying altered regulation of the recA gene was isolated as a revertant of a lexA3 recA200 double mutant which showed improved DNA repair and recombination functions. The mutant (alc-24) was located between srl and recA200 and caused synthesis of high levels of recA protein in both lexA+ and lexA3 strains. The possibility that alc-24 defines the regulatory site for recA is discussed.
