Protein

Bifunctional enzyme PyrF/PyrE

Gene

pyrFE

Organism
Nostoc sp. (strain PCC 7120 / UTEX 2576)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

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
Catalyzes the decarboxylation of orotidine monophosphate (OMP) to uridine monophosphate (UMP).By similarity

Catalytic activityi

Orotidine 5'-phosphate = UMP + CO2.
Orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate.

Cofactori

Magnesium.By similarity
