General annotation (Comments)

Function	Catalyzes the transfer of a ribosyl phosphate group from 5-phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP) By similarity.
Catalytic activity	Orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_01208
Cofactor	Magnesium By similarity.
Pathway	Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2. HAMAP MF_01208
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrE subfamily.
