Abstract |
The mutation drpA1 defines a new gene in Escherichia coli K-12 that maps at about 5.2 min. This mutation was obtained after enriching a population of cells for temperature sensitive dna mutations with the [3H]thymidine "suicide" technique followed by screening for mutants defective in transposon Tn5 precise excision. When growing cells carrying the drpA1 allele were shifted to the nonpermissive temperature, we showed that DNA, RNA, and protein syntheses shut off quickly, with the cessation of RNA synthesis occurring first. A recombinant plasmid between pBR322 and an HindIII fragment from wild-type E. coli restores the growth defect in drpA1 mutants. Using transposon Tn5 mutagenesis of this plasmid, we have been able to correlate the presence of a 68-kilodalton protein, as observed with the maxicell technique, with the ability of this plasmid to restore growth to drpA1 mutants.
