Abstract excerpt
Pseudomonas syringae BR2, a causal agent of bean wildfire, was subjected to Tn5 mutagenesis in an effort to isolate mutants unable to produce the beta-lactam antibiotic tabtoxin. Three of the tabtoxin-minus (Tox-) mutants generated appeared to have physically linked Tn5 insertions and retained their resistance to the active toxin form, tabtoxnine-beta-lactam (T beta L). The wild-type DNA corresponding to the...
