The Bacillus subtilis PerR repressor regulates the adaptive response to peroxide stress. The PerR regulon includes the major vegetative catalase (katA), an iron storage protein (mrgA), an alkylhydroperoxide reductase (ahpCF), a zinc uptake system (zosA), heme biosynthesis enzymes (hemAXCDBL), the iron uptake repressor (fur), and perR itself. A perR null strain is resistant to hydrogen peroxide, accumulates a porphyrin-like compound, and grows very slowly. The poor growth of the perR mutant can b ...[more]
