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 orotate from (S)-dihydroorotate (NAD(+) route): step 1/1.
CC -!- SUBUNIT: Heterotetramer of 2 PyrK and 2 PyrD type B subunits.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
