| Abstract |
Mutations in three Escherichia coli K-12 genes were isolated that reduce the efficiency of the lysine-inserting nonsense suppressor supL. These antisuppressor mutations asuD, asuE, and asuF map at 61.9, 25.3, and 76.3 min, respectively, on the E. coli chromosome. Biochemical and genetic analysis of the mutant strains revealed the reason for the antisuppressor phenotype for two of these genes. The activity of lysyl-tRNA synthetase was reduced in strains with asuD mutations. The modification of 5-methylaminomethyl-2-thiouridine, the wobble base of tRNALys, was impaired in asuE mutant strains, presumably at the 2-thiolation step. |
