marA, a regulated locus which controls expression of chromosomal multiple antibiotic resistance in Escherichia coli.

Journal of bacteriology - 1 Sept 1991

Hächler H, Cohen S P, Levy S B

Abstract excerpt

Stable chromosomal multiple-antibiotic-resistant (Mar) mutants of Escherichia coli, derived by exposing susceptible cells to low concentrations of tetracycline or chloramphenicol, express cross-resistance to structurally unrelated antibiotics. The entire resistance phenotype is reversed to susceptibility by insertion of transposon Tn5 into a locus, designated marA, near 34 min on the chromosome (A. M. George and...
