Orotate phosphoribosyltransferase (OPRTase, EC 2.4.2.10) catalyzes the Mg2+-dependent condensation of orotic acid (OA) with PRPP (5-alpha-d-phosphorylribose 1-diphosphate) to yield diphosphate (PPi) and the nucleotide OMP (orotidine 5'-monophosphate)

FAH (fumarylacetoacetate hydrolase) catalyses the final step of tyrosine catabolism to produce fumarate and acetoacetate. HT1 (hereditary tyrosinaemia type 1) results from deficiency of this enzyme. Previously, we prepared a partial mimic of the puta

Genetic fumarylacetoacetate hydrolase (Fah) deficiency is unique in that healthy gene-corrected hepatocytes have a strong growth advantage and can repopulate the diseased liver. Unfortunately, similar positive selection of gene-corrected cells is abs

A very mild method for the preparation of synthetically useful phosphonic dichlorides has been developed and its application toward the synthesis of 2-alkyl-2-oxo-1, 3, 2-dioxophosphorinanes and 1, 3-dimethyl-2-alkyl-2-oxo-1, 3, 2-diazaphospholidines

The dihydropyrrole 2 was synthesized in four steps from a protected lyxose derivative. This compound exists as one component of a complex equilibrium that may also contain the hydrated forms, 7 , as well as a dimeric form. The mixture comprises a pot

Phosphonate analogs of 5-phosphorylribose 1-α-diphosphate (PRPP), in which the anomeric oxygen has been replaced by carbon ( C -glycoside analogs), have been prepared in multistep syntheses. The exact “ribosyl” analog could not be elaborated fro

A mimic of the putative transition-state intermediate has been synthesized and found to be a very slow-onset inhibitor of yeast orotate phosphoribosyltransferase. The mechanism of inhibition may involve a rate-determining isomerization of the enzyme
