CC   -!- FUNCTION: Catalyzes the decarboxylation of orotidine 5'-monophosphate
CC       (OMP) to uridine 5'-monophosphate (UMP). {ECO:0000255|HAMAP-
CC       Rule:MF_01200}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + orotidine 5'-phosphate = CO2 + UMP;
CC         Xref=Rhea:RHEA:11596, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
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}.
