CC Note=Binds 1 [2Fe-2S] cluster per subunit.
CC {ECO:0000256|PIRSR:PIRSR006816-2};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC orotate from (S)-dihydroorotate (NAD(+) route): step 1/1.
CC {ECO:0000256|HAMAP-Rule:MF_01211}.
CC -!- SUBUNIT: Heterotetramer of 2 PyrK and 2 PyrD type B subunits.
CC {ECO:0000256|HAMAP-Rule:MF_01211}.
CC -!- SIMILARITY: Belongs to the PyrK family. {ECO:0000256|ARBA:ARBA00006422,
CC ECO:0000256|HAMAP-Rule:MF_01211}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01211}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
