BK11 (dnaKΔ2)
BK6 (dnaKΔ1)
  • a The strains were grown in GM17 supplemented with erythromycin at 30°C.

  • b Northern blotting was performed with 10 μg of total RNA from each strain. Specific mRNA species were detected with radioactive double-stranded DNA probes covering the gene of interest. Radioactivity was measured in each lane with a Packard Instant Imager.
