CC   -!- FUNCTION: Catalyzes the reduction of the double bond of an array of
CC       alpha,beta-unsaturated aldehydes and ketones. It also reduces the nitro
CC       group of nitroester and nitroaromatic compounds. It could have a role
CC       in detoxification processes. {ECO:0000255|HAMAP-Rule:MF_01614}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=A + H(+) + NADPH = AH2 + NADP(+); Xref=Rhea:RHEA:13149,
CC         ChEBI:CHEBI:13193, ChEBI:CHEBI:15378, ChEBI:CHEBI:17499,

CC       Name=FMN; Xref=ChEBI:CHEBI:58210;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01614};
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01614}.
CC   -!- SIMILARITY: Belongs to the NADH:flavin oxidoreductase/NADH oxidase
CC       family. NamA subfamily. {ECO:0000255|HAMAP-Rule:MF_01614}.
