CC -!- FUNCTION: Bifunctional enzyme catalyzing the last two steps of de novo
CC pyrimidine biosynthesis, orotate phosphoribosyltransferase (OPRT),
CC which converts orotate to orotidine-5'-monophosphate (OMP), and
CC orotidine-5'-monophosphate decarboxylase (ODC), the terminal enzymatic
CC reaction that decarboxylates OMP to uridine monophosphate (UMP).
CC {ECO:0000250|UniProtKB:P11172}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + orotidine 5'-phosphate = 5-phospho-alpha-D-
CC ribose 1-diphosphate + orotate; Xref=Rhea:RHEA:10380,

CC Evidence={ECO:0000250|UniProtKB:P11172};
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:0000250|UniProtKB:P11172};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:11597;
CC Evidence={ECO:0000250|UniProtKB:P11172};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC UMP from orotate: step 1/2. {ECO:0000250|UniProtKB:P11172}.
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC UMP from orotate: step 2/2. {ECO:0000250|UniProtKB:P11172}.
CC -!- SUBUNIT: Homodimer; dimerization is required for enzymatic activity.
CC {ECO:0000250|UniProtKB:P11172}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the purine/pyrimidine
CC phosphoribosyltransferase family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the OMP decarboxylase
CC family. {ECO:0000305}.
