  2. Phosphoribosyl pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphoribosyl_pyrophosphate

    Phosphoribosyl pyrophosphate (PRPP) is a pentose phosphate. It is a biochemical intermediate in the formation of purine nucleotides via inosine-5-monophosphate, as well as in pyrimidine nucleotide formation. Hence it is a building block for DNA and RNA.

    n/a Ensembl n/a n/a UniProt n a n/a RefSeq (mRNA) n/a n/a RefSeq (protein) n/a n/a Location (UCSC) n/a n/a PubMed search n/a n/a Wikidata View/Edit Human Hypoxanthine-guanine phosphoribosyltransferase (HGPRT) is an enzyme encoded in humans by the HPRT1 gene. HGPRT is a transferase that catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate. This ...

    en.wikipedia.org/wiki/Purine_metabolism

    Symptoms can include gout, anaemia, epilepsy, delayed development, deafness, compulsive self-biting, kidney failure or stones, or loss of immunity. Purine metabolism can have imbalances that can arise from harmful nucleotide triphosphates incorporating into DNA and RNA which further lead to genetic disturbances and mutations, and as a result ...

  5. Adenine phosphoribosyltransferase - Wikipedia

    Type II deficiency causes APRTase to have a reduced affinity for PRPP, resulting in a tenfold increase in the K M value. [6] It has been observed and studied primarily in Japan. [17] A diagnosis of APRTase deficiency can be made by analyzing kidney stones, measuring DHA concentrations in urine, or analyzing APRTase activity in erythrocytes.

    Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...

  7. Ribose-phosphate diphosphokinase - Wikipedia

    en.wikipedia.org/wiki/Ribose-phosphate...

    The product of this reaction, phosphoribosyl pyrophosphate (PRPP), is used in numerous biosynthesis (de novo and salvage) pathways. PRPP provides the ribose sugar in de novo synthesis of purines and pyrimidines, used in the nucleotide bases that form RNA and DNA. PRPP reacts with orotate to form orotidylate, which can be converted to uridylate (UMP

  8. Adenine phosphoribosyltransferase deficiency - Wikipedia

    en.wikipedia.org/wiki/Adenine_phosphoribosyl...

    Adenine phosphoribosyltransferase deficiency is a rare autosomal recessive metabolic disorder caused by mutations of the APRT gene. [5] Adenine phosphoribosyltransferase (APRT) catalyzes the creation of pyrophosphate and adenosine monophosphate from 5-phosphoribosyl-1-pyrophosphate and adenine.
