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}.
