Two fusions were identified which were induced late following treatment with sublethal concentrations of H2O2 (100 μM). The oxy-1 promoter was induced 4–5-fold and mapped to 11° while the oxy-2 promoter was induced 20-fold and mapped close to the right of the defective prophage PBSX, at about 120°. The oxy-2 fusion was induced by mitomycin C as well as H2O2, which correlated with the induction of PBSX by these agents. This was probably not a transcriptional induction, but rather a consequence of the induction of PBSX replication extending into adjacent regions of the chromosome. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-138-10-2061
