Resistance of Escherichia coli to penicillins: fine-structure mapping and dominance of chromosomal beta-lactamase mutations.
Seven Escherichia coli K-12 mutants with a lowered chromosomal beta-lactamase activity were analyzed genetically. The beta-lactamase-negative mutants isolated from ampA1-carrying strains (resistant to 10 microgram of ampicillin per ml) all carried genetic lesions very close to the ampA1 mutation, wh...
