CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000269|PubMed:10545205};
CC Note=Binds 1 FMN per subunit. {ECO:0000269|PubMed:10545205};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=28.9 uM for dihydroorotate {ECO:0000269|PubMed:10545205};
CC KM=185 uM for NAD(+) {ECO:0000269|PubMed:10545205};
CC Vmax=47.4 umol/min/mg enzyme {ECO:0000269|PubMed:10545205};
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:0000269|PubMed:10545205}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the dihydroorotate dehydrogenase family. Type 1
CC subfamily. {ECO:0000305}.
