Abstract

Gartner , T. K. (University of California, Santa Barbara), and E. Orias . Effects of mutations to streptomycin resistance on the rate of translation of mutant genetic information. J. Bacteriol. 91: 1021–1028. 1966.—The effects of mutations to streptomycin resistance of independent origin upon the translation of suppressible mutant information were studied in an isogenic series of strains of Escherichia coli . The group of suppressible mutants included 1 mutation in the z gene of the lac operon of E. coli (O 0 2 allele), 12 mutations distributed among the two r II cistrons of T4, and 13 mutations distributed among at least five cistrons of phage T7. It was concluded that the mutations to streptomycin resistance cause a significant decrease in the rate of translation of the suppressible codons, and that this effect is limited to a few types of codons.
