✦ Synopsis

cur-l, a mutation found in many strains of the Y10 line of Escherichia coli K-12, but not previously described, maps at 27 rain, close to galU. cur-1 causes mucoidity or uracil requirement at 29 ° C depending on the genetic background. These phenotypes are suppressed by amber codon suppressors.

Three independent relB mutants were studied. During amino acid starvation they all accumulate RNA and produce an inhibitor of in vitro protein synthesis; after starvation growth is retarded for hours. The mutants differ in the degree to which the common phenotype is expressed, but the characteristic

A temperature sensitive nonsense (TSN) mutant of E. coli K12 has been isolated in which a major bacterial protein is not synthesized at 42 degrees C. This protein is found in the parental strain at 42 degrees C and in cells rendered temperature resistant due to the insertion of a number of different
