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}.
