Summary
A temperature-sensitive mutant derived from an E. coli K12 strain, PA3092, was found to have an alteration in the ribosomal protein L19 (Isono et al., 1977). This mutant is a double mutant with a temperature-sensitivity mutation and a mutation leading to the structural alteration of L19 protein. Crosses with various Hfr strains and transductions with P1kc have revealed that the latter mutation maps at 56.4 min, between pheA and alaS. From the fact that two other mutations causing different types of alterations in L19 protein also map at this locus, the gene affected by these mutations was concluded to be the structural gene for the ribosomal protein L19 (rplS).
