Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression
Hepatology, EarlyView., 2022 Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Adenine Phosphoribosyltransferase Deficiency [PDF]
Clinical Journal of the American Society of Nephrology, 2012 Summary Complete adenine phosphoribosyltransferase (APRT) deficiency is a rare inherited metabolic disorder that leads to the formation and hyperexcretion of 2,8-dihydroxyadenine (DHA) into urine. The low solubility of DHA results in precipitation of this compound and the formation of urinary crystals and stones.

Kinetic Studies of Adenine Phosphoribosyltransferase [PDF]
Journal of Biological Chemistry, 1966 Abstract The mechanism of reaction of adenine phosphoribosyl-transferase from Ehrlich ascites tumor cells was investigated kinetically by initial velocity and product inhibition studies. The data are consistent with a mechanism in which 5-phosphoribosylpyrophosphate reacts with the enzyme to form an intermediate, presumably an enzyme-ribose 5-phosphate

Inflammation plays a critical role in 2,8-dihydroxyadenine nephropathy
Comptes Rendus. Chimie, 2021 Adenine phosphoribosyltransferase (APRT) deficiency is a genetic disease characterized by an increased production of 2,8 dihydroxyadenine (2,8-DHA) precipitating in urine, leading to a crystalline nephropathy and end-stage renal disease.

From Rate-Limiting Enzyme to Therapeutic Target: The Promise of NAMPT in Neurodegenerative Diseases
Frontiers in Pharmacology, 2022 Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the nicotinamide adenine dinucleotide (NAD) salvage pathway in mammals. It is of great significance in the metabolic homeostasis and cell survival via synthesizing nicotinamide
