Evaluation of the upregulation and surface expression of hypoxanthine guanine phosphoribosyltransferase in acute lymphoblastic leukemia and Burkitt’s B cell lymphoma [PDF]
Background The aim of this study is to determine whether Hypoxanthine Guanine Phosphoribosyltransferase (HPRT) could be used as a biomarker for the diagnosis and treatment of B cell malignancies.

Lesch-Nyhan Disease and Its Variants: Phenotypic and Mutation Spectrum of Hypoxanthine-Guanine Phosphoribosyltransferase Deficiency in Argentine Patients [PDF]
Hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency is a disorder of purine metabolism responsible for Lesch-Nyhan Disease (LND) and its variants, HPRT-related hyperuricemia with neurologic dysfunction (HND) and HPRT-related hyperuricemia ...

Purification and characterization of mouse hypoxanthine-guanine phosphoribosyltransferase.
Hypoxanthine-guanine phosphoribosyltransferase (HGPR transferase) (EC 2.4.2.8) has been purified approximately 4500-fold to apparent homogeneity from mouse liver. The procedure involves the use of affinity chromatography and was designed to be readily adaptable to small scale isolations.

Prioritization of Deleterious Variations in the Human Hypoxanthine-Guanine Phosphoribosyltransferase Gene [PDF]
Background and Objectives: Non-synonymous single nucleotide polymorphisms are typical genetic variations that may potentially affect the structure or function of expressed proteins, and therefore could be involved in complex disorders.

Restoring Ureagenesis in Hepatocytes by CRISPR/Cas9-mediated Genomic Addition to Arginase-deficient Induced Pluripotent Stem Cells [PDF]
Urea cycle disorders are incurable enzymopathies that affect nitrogen metabolism and typically lead to hyperammonemia. Arginase deficiency results from a mutation in Arg1, the enzyme regulating the final step of ureagenesis and typically results in ...

Evaluating Iso-Mukaadial Acetate and Ursolic Acid Acetate as Plasmodium falciparum Hypoxanthine-Guanine-Xanthine Phosphoribosyltransferase Inhibitors [PDF]
To date, Plasmodium falciparum is one of the most lethal strains of the malaria parasite. P. falciparum lacks the required enzymes to create its own purines via the de novo pathway, thereby making Plasmodium falciparum hypoxanthine-guanine-xanthine ...

Kinetic Isotope Effects and Transition State Structure for Hypoxanthine-Guanine-Xanthine Phosphoribosyltransferase from Plasmodium falciparum. [PDF]
Plasmodium falciparum parasites are purine auxotrophs that rely exclusively on the salvage of preformed purines from their human hosts to supply the requirement for purine nucleotides.

Case report: Whole exome sequencing identifies a novel variant in the HPRT1 gene in a male with developmental delay [PDF]
Lesch-Nyhan syndrome (LNS, OMIM #300322) is a rare X-linked genetic disorder caused by variants in the HPRT1 gene, which codes for the Hypoxanthine-guanine phosphoribosyltransferase (HGPRT).

Hypoxanthine-guanine phosphoribosyltransferase and inosine 5’-monophosphate dehydrogenase activities in three mammalian species: aquatic (Mirounga angustirostris), semiaquatic (Lontra longicaudis annectens) and terrestrial (Sus scrofa) [PDF]
Aquatic and semiaquatic mammals have the capacity of breath hold (apnea) diving. Northern elephant seals (Mirounga angustirostris) have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min ...

Kinetic Studies of Hypoxanthine-Guanine Phosphoribosyltransferase
Abstract The mechanism of reaction of human erythrocyte hypoxanthine-guanine phosphoribosyltransferase was investigated by initial velocity, product inhibition, and isotope exchange studies. Although initial velocity data are compatible with a mechanism involving binary enzyme-substrate complexes, the product inhibition and isotope exchange studies ...
