Proposed mechanism by which NOS activates respiration. (A) NO· generated due to NOS activity is rapidly decomposed into nitrite either spontaneously under aerobic conditions or through nitrate via Hmp and nitrate reductase activities. (B) Nitrite activates cytochrome bo-dependent respiration through an unknown mechanism and prevents metabolic dysfunction. (C) In the absence of NOS, SrrAB-dependent two-component signaling activates respiration and compensates for growth.
