Function
function
Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP).
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
- H+ + orotidine 5'-phosphate = CO2 + UMP
Cofactor
Pathway
Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2.
