UMPS '''N-terminal domain''' is an '''orotate phosphoribosyltransferase''' (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) or '''OMP decarboxylase''' which decarboxylates OMP to form UMP. Potent inhibitors of OPD are BMP – a barbituric acid derivative and xanthosine-5'-monophosphate (XMP). |
