CC -!- FUNCTION: Responsible for channeling the electrons from the oxidation
CC of dihydroorotate from the FMN redox center in the PyrD type B subunit
CC to the ultimate electron acceptor NAD(+). {ECO:0000255|HAMAP-
CC Rule:MF_01211}.
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01211};
CC Note=Binds 1 [2Fe-2S] cluster per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01211};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01211};
CC Note=Binds 1 FAD per subunit. {ECO:0000255|HAMAP-Rule:MF_01211};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC orotate from (S)-dihydroorotate (NAD(+) route): step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_01211}.
CC -!- SUBUNIT: Heterotetramer of 2 PyrK and 2 PyrD type B subunits.
CC {ECO:0000255|HAMAP-Rule:MF_01211}.
CC -!- SIMILARITY: Belongs to the PyrK family. {ECO:0000255|HAMAP-
CC Rule:MF_01211}.
