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   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
