Uridine 5'-monophosphate synthase
Uridine 5’-monophosphate synthase (UMPS) is a bifunctional enzyme catalyzes the formation of uridine monophosphate (UMP). UMPS N-terminal domain is an orotate phosphoribosyl transferase (OPRT) subunit which catalyzes the addition of ribose-phosphate to orotate forming orotidine 5’-monophosphate (OMP). The C-terminal subunit is orotidine 5’-phosphate decarboxylase (OPD) which decarboxylates OMP to form UMP.
