CC -!- FUNCTION: Is involved in NO detoxification in an aerobic process, CC termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and CC NAD(P)H to convert NO to nitrate, which protects the bacterium from CC various noxious nitrogen compounds. Therefore, plays a central role in CC the inducible response to nitrosative stress. CC {ECO:0000256|ARBA:ARBA00025094, ECO:0000256|HAMAP-Rule:MF_01252}.
