Discovery
Nitric oxide dioxygenase was discovered, and first reported in 1998, as an inducible O2-dependent enzymatic activity that protected bacteria against nitric oxide toxicity. The enzyme was identified with the E. coli flavohemoglobin.
More recently, another protein has been identified as a NO dioxygenase - rhodobacter sphaeroides haem protein (SHP), a novel cytochrome with NO dioxygenase activity. Although the biological function of SHP has yet to be identified, SHP has been shown, that with oxygen bound, it can react rapidly with nitric oxide to form nitrate.

“However backwards the world has been in former ages in the discovery of such points as GOD never meant us to know,—we have been more successful in our own days:Mthousands can trace out now the impressions of this divine intercourse in themselves, from the first moment they received it, and with such distinct intelligence of its progress and workings, as to require no evidence of its truth.”
—Laurence Sterne (1713–1768)
“The virtues of society are vices of the saint. The terror of reform is the discovery that we must cast away our virtues, or what we have always esteemed such, into the same pit that has consumed our grosser vices.”
