✦ Synopsis

A temperature sensitive mutant, termed JE1306, derived from Escherichia coli strain PA3092 was found to have an alteration in the ribosomal protein L25. Crosses with various Hfr strains and transductions with P1 kc phage have revealed that the mutation maps at 47.3 min between nalA and fpk, in a region where no ribosomal protein gene has so far been located. The gene affected by this mutation is most probably the structural gene for protein L25 (rplY), because a strain heteromerozygous for the region shows both wild type and mutant forms of protein L25.

A mutant of E. coli selected for temperature-sensitive growth on rich medium harbored an altered ribosomal protein S6 (Isono et al., 1976). This mutant was found to possess at least two mutations, one being responsible for the temperature-sensitivity and the other for the S6 alteration. Crosses with
