WebAug 8, 2008 · Introduction. Adenine phosphoribosyl-transferase (APRT) is the key enzyme that transforms adenine into adenylate monophosphate (AMP). In case of APRT deficiency, xanthine oxidase rapidly oxidizes adenine into 2,8-dihydroxyadenine (2,8-DHA), which is then eliminated by the kidneys through tubular secretion. 2,8-DHA is insoluble at a … WebIn the absence of APRT, xanthine dehydrogenase (XDH) converts adenine into 2,8-dihydroxyadenine (2,8-DHA), a compound that is highly insoluble in urine. Acute kidney injury may occur from urinary tract obstruction by calculi, and chronic kidney disease is a common sequela caused by crystalline nephropathy.
