CC ChEBI:CHEBI:57538, ChEBI:CHEBI:57865; EC=4.1.1.23;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01200};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC UMP from orotate: step 2/2. {ECO:0000255|HAMAP-Rule:MF_01200}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01200}.
CC -!- SIMILARITY: Belongs to the OMP decarboxylase family. Type 1 subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01200}.
