CC   -!- FUNCTION: Catalyzes the conversion of dihydroorotate to orotate with
CC       quinone as electron acceptor. {ECO:0000255|HAMAP-Rule:MF_00225}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(S)-dihydroorotate + a quinone = a quinol + orotate;
CC         Xref=Rhea:RHEA:30187, ChEBI:CHEBI:24646, ChEBI:CHEBI:30839,
CC         ChEBI:CHEBI:30864, ChEBI:CHEBI:132124; EC=1.3.5.2;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00225};
CC   -!- COFACTOR:
CC       Name=FMN; Xref=ChEBI:CHEBI:58210;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00225};
CC       Note=Binds 1 FMN per subunit. {ECO:0000255|HAMAP-Rule:MF_00225};
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC       orotate from (S)-dihydroorotate (quinone route): step 1/1.
CC       {ECO:0000255|HAMAP-Rule:MF_00225}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00225}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00225};
CC       Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_00225}.
CC   -!- SIMILARITY: Belongs to the dihydroorotate dehydrogenase family. Type 2
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00225}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAC18453.1; Type=Erroneous initiation; Evidence={ECO:0000305};
