The anti-sigma factor MucA of Pseudomonas aeruginosa: dramatic differences of mucA22 vs. DmucA mutants in anaerobic acidified nitrite sensitivity of planktonic and biofilm bacteria in vitro and during chronic murine lung infection
Ontology highlight
ABSTRACT: In this study, the A-NO2- sensitivity of mucA22 mutant bacteria vs. a genome sequence-confirmed mucA deletion (∆mucA) mutant was determined. The ∆mucA is surprisingly more resistant to A-NO2- than mucA22 bacteria. The genes responsible for the disposal of nitric oxide (NO), a by-product of A-NO2-, were found to be near wild-type levels in the ∆mucA mutant yet were dramatically reduced in the mucA22 mutant.
