Function
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
- orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate
Cofactor
Pathway
Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2.
