RT estrogens in aquatic ecosystems.";
RL Submitted (JUN-2016) to the EMBL/GenBank/DDBJ databases.
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}.
CC -!- CATALYTIC ACTIVITY:
