Figure 5. Hcp is important for NO· detoxification and resistance to NO·-mediated inhibition of respiration.

Figure 5

Concentrations of O2 (black line) and NO· (red line) were measured using O2 and NO· probes as described in Experimental Procedures. Respiration was stimulated in S. Typhimurium cells by the addition of 0.1% glucose at T = 1 m. After 50% of the saturated oxygen was consumed, ProliNO, a rapidly-releasing NO· donor, was added to a concentration of 5 mM, and O2 and NO· concentrations monitored. A. Wild-type (WT). B. nsrR.
