CC   -!- FUNCTION: Catalyzes the reduction of FMN to FMNH2 which is used to
CC       reduce pyrimidine by RutA via the Rut pathway. {ECO:0000255|HAMAP-
CC       Rule:MF_00833}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=FMNH2 + NAD(+) = FMN + 2 H(+) + NADH; Xref=Rhea:RHEA:21620,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57618,
CC         ChEBI:CHEBI:57945, ChEBI:CHEBI:58210; EC=1.5.1.42;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00833};
CC   -!- INDUCTION: Up-regulated by the nitrogen regulatory protein C (NtrC also
CC       called GlnG) and repressed by RutR. {ECO:0000255|HAMAP-Rule:MF_00833}.
CC   -!- SIMILARITY: Belongs to the non-flavoprotein flavin reductase family.
CC       RutF subfamily. {ECO:0000255|HAMAP-Rule:MF_00833}.
