In order to determine the metabolic role of RNase D in Escherichia coli, we have attempted to isolate strains deficient in this enzyme. One strain containing a temperature-sensitive RNase D was found among a heavily mutagenized stock of strain temperature-sensitive for growth. Genetic mapping of the

โฆ Synopsis
A putative temperature-sensitive transcription mutant described earlier (Jabbar and Jayaraman, 1976) has been genetically mapped. The locus maps at 38 min to the left of aroD. The mutation is recessive to the wild type and it affects a gene probably other than the genes coding for the alpha and beta subunits of phenylalanine tRNA synthetase and protein synthesis initiation factor IF-3 which also map in the same region.

Two factor transductional crosses place recF at approximately 82 min on the E. coli chromosome; recF is highly cotransducible with dnaA and gyrB (cou). Transductional analysis with a series of lambda tna specialized transducing phages carrying chromosomal DNA from the tnaA region place recF between
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
Temperature-sensitive (ts) mutations were isolated within a ribosomal protein gene (rpsL) of Escherichia coli K12. Mutations were mapped by complementation using various transducing phages and plasmids carrying the rpsL gene, having either a normal or a defective promoter for the rpsL operon. One of
