CC   -!- CATALYTIC ACTIVITY: (S)-dihydroorotate + O(2) = orotate +
CC       H(2)O(2).
CC   -!- COFACTOR: Binds 1 FMN per subunit (By similarity).
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo
CC       pathway; UMP from HCO(3)(-): step 4/6.
CC   -!- SUBUNIT: Heterotetramer of 2 pyrK and 2 pyrD subunits (By
CC       similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the dihydroorotate dehydrogenase family.
CC       Type 1 subfamily.
