RT   "Complete sequence of Klebsiella variicola At-22.";
RL   Submitted (FEB-2010) to the EMBL/GenBank/DDBJ databases.
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,
