Bacterioferritin A modulates catalase A (KatA) activity and resistance to hydrogen peroxide in Pseudomonas aeruginosa.

Purified KatA has an apparent Km for H2O2 of 44.7 mM; katA complements catalase-deficient E. coli.

"apparent Km for H2O2 of 44.7 mM"
katA mutants lack catalase activity and are hypersusceptible to H2O2.

"Isogenic katA and bfrA mutants were hypersusceptible to H2O2"

Catalase (KatA) plays a role in protection against anaerobic nitric oxide in Pseudomonas aeruginosa.

KatA heme binds NO directly; katA mutants are sensitive to anaerobic NO.

"KatA has a 5-coordinate high spin ferric heme that binds NO without prior reduction of the heme iron"
