| Function | Catalyzes the transfer of a ribosyl phosphate group from 5-phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP). |
| Catalytic activity | RHEA:10380: diphosphate + orotidine 5'-phosphate = 5-phospho-alpha-D-ribose 1-diphosphate + orotate
EC 2.4.2.10 |
| Cofactor | Mg(2+) |
| Pathway | Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2. |
| Subunit | Homodimer. |
| Similarity | Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrE subfamily. |
