Phosphoribosyl pyrophosphate pentasodium

CAS No. : 108321-05-7

MCE 国际站：Phosphoribosyl pyrophosphate pentasodium

产品活性：Phosphoribosyl pyrophosphate (PRPP) pentasodium 是嘌呤和嘧啶核苷酸、氨基酸组氨酸和色氨酸以及辅助因子 NAD 和 NADP 生物合成所需的重要代谢物。

研究领域：Metabolic Enzyme/Protease

作用靶点：Endogenous Metabolite

In Vitro: Phosphoribosyl diphosphate (PRPP) pentasodium is an important intermediate in cellular metabolism. PRPP is synthesized by PRPP synthase, as follows: ribose 5-phosphate + ATP → PRPP + AMP. PRPP is ubiquitously found in living organisms and is used in substitution reactions with the formation of glycosidic bonds. PRPP is utilized in the biosynthesis of purine and pyrimidine nucleotides, the amino acids histidine and tryptophan, the cofactors NAD and tetrahydromethanopterin, arabinosyl monophosphodecaprenol, and certain aminoglycoside antibiotics.
?Phosphoribosyl diphosphate (5-Phosphoribosyl-l-pyrophosphate) pentasodium, a substrate shared by adenine phosphoribosyltransferase and hypoxanthine-guanine phosphoribosyltransferase, accumulates in human erythrocytes lacking hypoxanthine-guanine phosphoribosyltransferase. 5-Phosphoribosyl-l-pyrophosphate added to purified adenine phosphoribosyltransferase stabilizes it against heat inactivation.
