CC   -!- FUNCTION: Catalyzes the conversion of dihydroorotate to orotate with
CC       fumarate as the electron acceptor. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(S)-dihydroorotate + fumarate = orotate + succinate;
CC         Xref=Rhea:RHEA:30059, ChEBI:CHEBI:29806, ChEBI:CHEBI:30031,
CC         ChEBI:CHEBI:30839, ChEBI:CHEBI:30864; EC=1.3.98.1;
CC   -!- COFACTOR:
CC       Name=FMN; Xref=ChEBI:CHEBI:58210; Evidence={ECO:0000250};
CC       Note=Binds 1 FMN per subunit. {ECO:0000250};
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the dihydroorotate dehydrogenase family. Type 1
CC       subfamily. {ECO:0000305}.
