orotidine 5′monophosphate

Orotidine 5′-monophosphate, a pyrimidine ribonucleoside, functions as an endogenous metabolite in human, E. coli, and mouse processes. It serves as an intermediate in uridine monophosphate (UMP) biosynthesis and is utilized in researching the mechanism of orotidine 5′-monophosphate decarboxylase.

Orotidine 5'-monophosphate trisodium, a pyrimidine nucleotide, is synthesized through the de novo DNA synthesis pathway by various microorganisms, including M. tuberculosis, S. cerevisiae, S. typhimurium, and P. falciparum. The compound's production involves orotate phosphoribosyltransferase (OPRT)-catalyzed reactions using phosphoribosyl pyrophosphate (PRPP) and orotic acid (OA) as substrates [1].

Orotidine-5'-monophosphate-CoA (Orotidine-5'-monophosphate-coenzyme A) is a derivative of coenzyme A.

5-Fluoroorotic acid (monohydrate) (5-Fluorouracil-6-carboxylic acid Mono(hydrate); 5-FOA) is employed to detect the expression of the URA3 gene in yeast molecular genetic constructs. Yeast possessing an active URA3 gene (which encodes orotidine-5'-monophosphate decarboxylase) convert 5-FOA into 5-fluorodeoxyuridine, a substance toxic to cells. Yeast strains with mutations in the URA3 gene that confer resistance can grow in the presence of 5-FOA if uracil is added to the medium.

Uridine-5'-monophosphate (UMP) is a ribonucleotide.1It is formedviadecarboxylation of orotidine-5'-monophosphate (5'-OMP) by OMP decarboxylase. UMP is further phosphorylated by UMP-CMP kinase to form UDP and UTP during nucleic acid biosynthesis. Formulations containing UMP have been used as dietary supplements. 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Nucleotide BiosynthesisBiochemistry(2002)
