>TIGR00336 pyrE orotate phosphoribosyltransferase; InterPro: IPR004467 Orotate phosphoribosyl transferase (OPRTase) is involved in the biosynthesis of pyrimidine nucleotides. Alpha-D-ribosyldiphosphate 5-phosphate (PRPP) and orotate are utilised to form pyrophosphate and orotidine 5 -monophosphate (OMP) in the presence of divalent cations, preferably Mg2+. In a number of eukaryotes, this protein is fused to a domain that catalyses the reaction (4.1.1.23 from EC). The combined activity of 2.4.2.10 from EC and 4.1.1.23 from EC is termed uridine 5 -monophosphate synthase. The conserved Lys (K) residue at position 101 of the seed alignment has been proposed as the active site for the enzyme.; GO: 0004588 orotate phosphoribosyltransferase activity, 0006221 pyrimidine nucleotide biosynthetic process.
