CC Evidence={ECO:0000256|HAMAP-Rule:MF_00220};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00220};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC (S)-dihydroorotate from bicarbonate: step 3/3. {ECO:0000256|HAMAP-
CC Rule:MF_00220}.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
