CC -!- FUNCTION: Anaerobic nitric oxide reductase; uses NADH to detoxify
CC nitric oxide (NO), protecting several 4Fe-4S NO-sensitive enzymes. Has
CC at least 2 reductase partners, only one of which (NorW, flavorubredoxin
CC reductase) has been identified. NO probably binds to the di-iron
CC center; electrons enter from the NorW at rubredoxin and are transferred
CC sequentially to the FMN center and the di-iron center. Also able to
CC function as an aerobic oxygen reductase. {ECO:0000255|HAMAP-
CC Rule:MF_01312}.
